Technically speaking, simply sending presence to a MUC and joining (thus getting the history and participants) are not the same thing. Sending a proper MUC join (with the <x/> and the history control optionally inside it) to M-Link[*] will, therefore, give you the history you asked for, and all the occupant presence, even if you're already in the room. I find this *extremely* useful - which is why I did things that way. A use-case for this is where an S2S link is down when you reconnect your C2S, or the server crashes, or ... - all arguably edge cases, but they're solved very nicely this way. Other servers don't do this, though - I think they should. If you wanted to avoid the occupant presence, you'd want an extension which signalled this in much the same way that the history controls work.
