When I propose the merge of two profiles, I get a box to enter my reasoning for the merge, and the managers of the profiles receive an email notification of the merge request.
When I propose an unmerged match of two profiles, I get no box for my reasoning*; I have to manually comment on both of the profiles to explain why I think they could be the same person and what discrepancies keep me from proposing the merge. And the profile managers don't receive an email notification; at most, they get a note buried in the WikiTree Family News email, easily missed.
If someone proposed merges on profiles I manage and I missed the email, I can go to "Pending Merges awaiting action from me" to see what needs work. I can't, as far as I can tell, see a list of all the profiles I manage that have Unmerged Matches.
Why are merges and matches treated so differently?
We've had regular complaints about the number of unmerged matches that never get resolved. But as long as there's that extra hurdle to explain why it's an unmerged match rather than a merge proposal, and as long as it's hard for profile managers to *find* their profiles that have unmerged matches, profile managers aren't going to fix them.
* I do get a box if I'm changing a merge proposal to an unmerged match. But I should get one from the beginning.
