Re: [xmpp] 3921bis: probe + unavailable

While I agree this would simplify the protocol a little, I am not convinced
it is a change worth making.

First of all, not responding to probe when unavailable is a pretty good
optimization. A large part of Xmpp traffic is presence. This change would
further significantly increase the presence traffic, making scaling more
challenging and adding load to c2s and s2s connections. For example, a cell
phone xmpp client may be better off not getting potentially thousands of
presence unavailable stanzas for offline friends when connecting over gprs.

I'm also not convinced this change make it significantly easier to implement
xmpp clients/servers. Especially if we are going to recommend that clients
and servers SHOULD cope with no response for legacy reasons.
