As separately detailed, there are no burdens placed on any
clients; a client would not be required to implement recognition
of the proposed ESMTP keyword(s).  In the absence of any
client implementation (or if implemented but ignored) the
submit server would be free to make modifications as is now
the case by virtue of the administrator whispering "this is
a submit server" inside an anechoic chamber.  The difference
is that there would be a provision which would provide a
clear differentiation of a submit server from an MTA; a
differentiation which has been claimed to exist but which
can be found nowhere in RFC 2476 or its draft successor.

No, it's merely an ESMTP keyword.  It provides a "deterministic
means" of identifying a submission server; that was the intent
of the ESMTP keyword -- additional verbs provide for control
of munging by client-server negotiation which arose later in
our dialog.

As discussed, the "deterministic means" claimed in the draft
for identifying submission seems to be lacking (a.k.a. "broken").

I have no problem in developing either a draft or text that
could be incorporated in a future revision of the draft
under discussion (I note that a -01 version has already
been produced).  If separate from the 2476 successor, that
should probably happen in an IETF WG, but I see no active
WG for such work.
