I was told that this is the most appropiate repository for this.
I generally wish to be known by my global displayname, but there are a few rooms where I would like to have a different name and then there are a few dozen rooms where I would like to be known by my full name as they are somewhat professional. Currently when I change my display name in Element by /nick, the rooms that I have a separate name in get overwritten and then I have to start going through them by /myroomnick again.
This also affects room specific avatars.
AFAIK synapse changing m.room.member event in all rooms you are in when changing profile is actually behaviour not mentioned in the spec - the spec doesn't say what servers should do if you change your profile information
So, while there is a need to clarify that, it is also a good idea to make local room changes "sticky".
