The servers I'm familiar with (Freenode, Quakenet) all make you appear to part or quit when you apply a cloak.
However, without nick it is not unique, which would give the same problems as non-anonymous XMPP MUCs, where we can not distinguish different instances of the same JID. There too we should find a better way to ID users.
