The XMPP Extensions Editor has received a proposal for a new XEP.
Title: Recipient Server Side Notifications Filtering
Abstract: This specification defines a modern efficient way to deliver PubSub
notifications.

The XMPP Council will decide in the next two weeks whether to accept this
proposal as an official XEP.
I've finally made time to read this proposal.
It seems to me that the proposal is saying that PEP isn't always ideal,
so we need a new protocol. However, I think that for high-scale
scenarios (e.g., a bot collecting geolocation information about all
users in a large company, or microblogging for users with lots of
followers), it might be better to use generic pubsub (XEP-0060) without
presence involved at all, not PEP (which as noted depends on having
bidirectional presence subscriptions in place). PEP is a simplification
of pubsub for IM systems, but not all pubsub systems are based on IM.
However, a system could be architected such that it provides two ways to
subscribe to the same information (via pubsub and PEP). Or a system
could implement full pubsub on every JID, instead of using the
simplified technology we defined in the PEP spec. I'm not, however,
seeing the need for a completely new protocol.
Just my centigram of silver...
