Reading the Internet Draft, I'm a little puzzled by:

    4.3.  Additional state required on the server

    [...]

    Also note that if the UIDVALIDITY of the mailbox changes [...], then
    any state associated with expunged messages MUST be deleted as well.

I'm not clear what the motivation is here given that a new UIDvalidity 
forces a full resync from any client: no QRESYNC is possible.

This requirement is likely to be a pain for:

Given that unexpunge assigns a new UIDvalidity to the mailbox.
