This could require the IMAP server fetch the entire contents of a
message before processing something as simple as a FETCH FLAGS command.

Also, much of sieve would be otherwise useless (fileinto, keep, etc).

It'd also require sieve be available to dovecot, which it isn't (yet). 

AS an implementation point, poisoning the IMAP queries would probably be
easier- and currently, wouldn't require any architectural changes
(except to support matching multiple folders).
