MUA would have to support both of those URLAUTH and BURL extensions, so
that it can register a temporary URL on the IMAP server, then connect to
SMTP server and give that URL to BURL command (instead of sending the
mail with DATA command).

So from MUA's point of view it's basically the same as before: save to
IMAP and after that send via SMTP.

Yeah, he probably isn't interested in adding IMAP client support for
Postfix, although it could be pretty basic support.
