I agree it's odd.  I still think we should do it.  "MUST accept"
because there's a lot of software that generates it and will continue
to, so failure on that point affects interoperability.  "MUST NOT
generate" because there's no reason to allow generation (there are
better equivalents) and allowing more than FRC 2822 (it says "MUST NOT
generate") is something we ought to do only with very good reason;
oddness of wording isn't such a reason.
