Noting that the logic above is the same, anyone want to make a

dependent on it as are other options that people in many part of
the world consider important (e.g., SMTPUTF8), and it is
therefore time to just deprecate HELO.

With a clearer split between SMTP and submission, that seems sensible. Submission can excuse all sorts of antique stuff that SMTP wouldn't.
