Yes, of course. There are possible scenarios, I think, without this
cooperation, but I suspect they would be sources of headaches more than

Yes. I ask about this scenario because it is already in use in the mail
world. But the problem is a bit different there, because the mail
user-agent doesn't know the suscriber list, and sometimes can't (or
can't have a exhaustive one).

IIUC, with MUC, the Jabber end user always know who is in the room, so
this could be avoided.

This is the lesser secure scenario, but the easier one and the only able
to scale to any number of participants in the room, also. This is the
main reason I think it should exist.
