Matthieu Baechler commented on JAMES-3406:
------------------------------------------
> To be honest, documentation should describe what we have, not what we could
> possibly have.
I completely agree
> As such, I think it's premature to advertise a Multi DC Cassandra based IMAP
> server.

helps people to understand why we don't have X or Y yet.
