For direct TCP connections: yes.

But in something like XMPP, there is no "connection" where you can
negotiate things. Even worse: servers cache messages, so whenever you
get "online", there is no way that you know which kind of messages are
sent to you, unless every message contains the info like the protocol
version. Heck, you can get old crap from a year ago, when the world was
totally different.

If the future, I hope we don't send any XML over the wire anyway, so
then this isn't as much as a problem (in terms of wasted bytes).
