As a person who works with XMPP, I can say with some degree of authority that MUCs are, indeed, an abomination. Everything about them is broken: the roles and affiliations model, and the concept of connecting to it in the IRC-channel style which is a non-starter on mobile clients which can't be connected all the time.

So we actually dropped support for MUCs and created our own Group chat protocol, which even provides a fallback compatibility with the very basic XMPP. Extensibility for the win!
