What server out there can a PubSub component use that doesn't automatically process messages in accordance with the XMPP IM rules? So, in order to deliver message the PubSub component needs to (in essence) have a it's own message processer, rather than relying on the existing ones - to do otherwise will cause things to fail (and notifying the wrong resource is, any way you cut it, a failure) for resource based subscriptions.

Come, on. This is not true. Did you read the rest of my mail. I proposed
we solve this by integrating JEP-0079 (AMP). That accomodates your
problem nicely.
