#1174 Allow server admins to request MUC ownership when needed
Description of feature:
As a server admin, I would like to be able to request ownership of a MUC when needed, and not have it on all the time.
Kind of like IRC, but not caused by its limitations.
Out of all the rooms I'm in, as server admin, I almost never need more than a participant role.
As a nice side-effect, that would also help avoid me seeing all these realjids flying around, since full-anon MUCs are not a thing.
