Mike,
I'm glad we're not at odds, and agree that good discussions are great -- I've already learned a lot in this one and hope to go on doing so.
Using the same strategy, I am mystified how you would record an obituary such as :-
"Fred Summer was survived by his wife June Summer. The same minister conducted the burial as their marriage."
or any other ceremony for which no details exist other than you are comfortable it did actually happen.
I'd create a source for the obituary (with text from the source, or a media image if it existed). I'd cite that source for the Status of a Marriage (default) relationship (more on citing the source later) either as the first piece or an additional piece of evidence. I'm not a fan of Assessments on a source -- I'd rather follow the Evidence Analysis Process Map (as per
https://www.evidenceexplained.com/conte ... rocess-map) -- but if I had to choose one in the absence of the ability to add a note to the Status, I'd choose Questionable until and unless I could corroborate the evidence from the obituary for the marriage having taken place with evidence from other sources -- a marriage record, a newspaper report on the wedding, etc. to convince me (as far as possible) that the marriage really did happen (rather than being simply 'reported' to keep family and neighbours or the census enumerator happy, so to speak.) I wouldn't create a marriage event until I could identify a timeframe (better than birth to death

) by calculation, estimation or exact specification (I could live without place in those cirumstances).
Of course the same obituary would also be a source for death and burial/cremation/whatever; and an obituary date gives better clues about the date of death/burial (even if it isn't explicit) than it does about any marriage ceremony (unless it says something like "Fred was survived by his wife of 44 years, Mary.") So much depends on what the source actually says... if the obituary doesn't help determine when the individual died (undated newspaper clipping that refers to a funeral 'last Wednesday') and I don't have any other evidence, I wouldn't enter a death event -- it doesn't add a whole lot of value to record that somebody is 'deceased' without extra information or evidence, even if you know they're most probably deceased because of time elapsed; and it wouldn't help me to conform with with my own Privacy Policy:
"I do not publish the names or any other details of living individuals on this site, except to show their places (without names) in the family tree; this includes individuals born within the last 100 years whom I do not know to be dead. In addition, I do not publish any details of individuals born from 1930 onwards, including myself."
A custom Obituary event might be the way to go, but I'd need to think about that some more (and would rather try tracking down corroboration of death/disposal first).
I just fail to see how entering a Status, that cannot directly have a Source Citation, is better than entering an Event/Attribute (with no details except perhaps a Note on its provisional nature), that can have a Source Citation, and avoids all the 'problematic stickiness' agreed with Adrian.
See later (again) on citations on statuses.
I prefer not to enter an event until I have a reasonable degree of confidence that it did happen. Creating a Marriage event without confirming that the marriage occurred doesn't seem right.... and if you've searched for a marriage event without success and concluded that there was no such event, how do you record that except as a status ("Unmarried Couple") with a source, which would probably be your own notes about the unsuccessful search, unless you were lucky enough to be able to quote a scholarly article explaining why the marriage is a historical figment. Not that any of my ancestors are important enough to warrant a scholarly article, although I do know of a published article which supports the argument that my great-great-grandmother was named incorrectly in the Parish Register at her marriage, so she really isn't Eleanor Hassall but some unknown other Eleanor.
The direct corollary would be a Status for Individual records for similar uncorroborated facts
Not sure I follow you here. I only document an individual attribute or event (or indeed a family attribute or event) if the evidence from sources support it, for example multiple sources corroborate the fact or there's a single 'strong' source to support it; and I've done a reasonably exhaustive search to eliminate other possibilties; and I've considered conflicting evidence and can explain why I've 'disregarded' that conflicting evidence. (As an aside, a custom attrtibute for a family might do the same job as Status, but would have all the same drawbacks in terms of customisations as other approaches that don't use the Status fields).
Regarding the Source Citation for the Status it is definitely on the <whole record> for the Family record. In the Family record Property Box on the All tab, the Source item is at same level as Status item. If you click on either the record name on first line or the Status item, the Sources For pane says <whole record>.
I see something diffeent... If I click on the record name, I see Sources for Whole record and the source I've cited for the Status doesn't appear. If I click on the Status I see Sources for Marr. (Name 1 _ Name 2) and the source I've cited for the Status appears, even though the Source is shown subordinate to the Family records not the Status. Weird.
How would you record a relationship for which you don't have an event except by creating a unsourced event?
I can't see how that situation arises. If it is unsourced then how do I know the relationship. There must be some source that identifies the relationship. Anyway, I would either create an Event with no details except a Note and whatever Source was available, or create a record level Note that could have a direct Source. It is just the same as I would create an Individual fact in similar circumstances, because there is no Status field for Individual records.
I'm thinking of the situation when a source supports the relationship ("married") but not the marriage event -- you may believe that the Marriage probably took place, but all you can record is the relationship status until you find more information about the marriage. If you didn't use status, you would have to create a dummy Marriage event or a record level Note, as you say -- but neither of those (IMO) are satisfactory in terms of data entry, reporting or analysis.
