You're apparently not looking at the right users. RedHat has been using procmail as the default local delivery agent for a very long time.
Independent of procmail/sieve, you're also assuming that the users never access their mail except via IMAP, and therefore that the usenet-like storage model used by cyrus is not an issue; and, that no existing mailboxes will have to be imported into the cyrus structure.
