I understand the use case, but I think they put it in the wrong
protocol. It should have been placed in the IMAP protocol. You have the
benefit of referencing mails, but no intermixing of SMTP and IMAP, or
authentication complexities.
In fact, some IMAP servers already support IMAP sending through a "magic
Outbox folder".
