I should mention also that Bron has been talking for some time now about
storing modseqs on per-message annotations as a way to make replication
more efficient.  I think this is an excellent idea and is easy enough to
do, because we have a good modseq counter with sensible semantics for
the mailbox and could store it in the db in a semi backwards compatible
manner, and the CONDSTORE rfc allows for servers to keep separate
modseqs on any kind of per-message data.  Once we do that, it would be
relatively easy to emit unsolicited ANNOTATION responses.

It might be feasible to do similar things for per-mailbox annotations. 
But per-server annotations are...less obvious.
