The roster is, in the sense that items can be atomically added and

But when you change the list, you only need to change the delta.
It would be nice if someone wrote a JEP for a new protocol with these
* Uses the same data as JEP-0049 (existing protocols such as bookmarks
can be used with both the old and the new protocol)
* Add items (without resending everything)
* Receive notifications on changes
* Remove items matching given criteria
* Update an item identified by certain "key" attributes
But I think I read about someone proposing to use SPPS^H^H^H^H PEP for
that - that might work.
