Sorry for not responding earlier, I've been doing two conferences (XTech
and one of the Dutch Unix User Group), talking about Jabber.

Response to the whole thread below.

What others have tried to explain and some still seem to have failed to
grasp is this:

The pubsub JEP was defined on top of XMPP Core, not on top of XMPP IM.
That means that it doesn't know/care about resource/priority based
routing and offline message storage. Lather. Rinse. Repeat.

Exactly my thoughts. We could define a node and/or subscription option
to integrate this *optionally*.
