Jamie, here is an example of why the reject messages would be helpful on both profiles, since there are no comments being posted to both profiles.
In Aug 2021, I proposed unmerged match, which did NOT post a comment on the profiles. I posted a comment on both profiles so the PMs were aware of the problem so research could be done.
Someone made changes in Jan 2023 to both profiles, so now they do not look the same.
When one PM stated that they are not the same, I replied to his message that they are now different 'because of the changes', so those comments are on one profile.
When I rejected the merge, the reject message is only seen on the other profile, but it is not on the profile that I had replied to, so the other PM, or anyone reviewing that profile or the comments will not see the reject message.
