Now if we want to move contacts into pubsub anyway it feels like what we
really want is boomarks3:
Bookmarks 3: The Revenge Of PEP?
(From XEP-0402: This specification was originally entitled "Bookmarks 2: This Time It's Serious". Any implication of a sense of humour has been removed with the change in title.)
Bookmarks 2 has to only store chatrooms because it's built around the same syntax as Bookmarks 1.
There's no reason not to put all contact-stuff into a single pubsub node - after all, not so long ago we were looking to put it all into the roster.
Dave.
