This seems like the same arguments that could be used for telnet, ftp and rcp.
I don't see us doing a bis document for ftp.
I don't understand your point. Of course we're not doing a bis

But they are all optional extensions, not part of SMTP, which is why I
don't want them cluttering up the SMTP spec.
These extensions are "optional" as much as Paul@xxxxxxxxx and
