The reason that message submission is done with SMTP is because of the number of SMTP extensions that the MUA will want to use, in particular DSNs, deliver-by, deliver-after, message tracking, and whatever else may be invented in the future. If you want to make message submission a part of IMAP and POP then you'll have to re-do all these SMTP extensions twice, which is a colossal waste of time.
