Actually, this could probably be safely implemented by sending all of the state to the client as a string:

* OK [SAVEDSTATE base64-encoded-state]

There isn't a whole lot of state to be saved really. Mailbox GUID, UIDVALIDITY, HIGHESTMODSEQ gives the mailbox state. Then you have the language/etc. states. Clients could restore their earlier state from days ago, as long as Dovecot still has the necessary .log records available (similar to how QRESYNC works).
