It simply makes no sense to me to have an Intermediate Client spec that
mandated MUC and not have an equivalent Intermediate Server spec that
matches up with the client spec. Talk about sending a mixed message to the
I think MUC is important enough and so universally implemented that it
deserves to be in an intermediate spec. I definitely agree that testing
should be against a distribution not just the pure XMPP server.
