Right, I always knew that strcmping server names or JIDs to decide how
to behave was totally wrong, but if the server isn't service
discoverable there aren't many alternative ways to discover features.

Even if we're not doing google:roster, then there are other places where
we need to know if the server has extra features (google:relay auth
token, off the record, mail notifications...) or does not quite behave
according to the standard in places (<presence type="unavailable">
behaves like invisible, so the server sends us presence, messages and
iqs... something like <feature
var='presence-unavailable-behaves-like-invisible'/>). It would be very
nice if you could respond to discovery requests for at least some of
these behaviours... :)
