This comment was added as a follow-on note.  Sorry for not being clear.

Accepting messages from a domain lacking MX records might be risky
due to the high rate of domain turnovers.  Within a few weeks, more
than the number of existing domains will have been added and deleted
by then.  Spammers take advantage of this flux.  Unfortunately SMTP
server discovery via A records is permitted and should be
deprecated.

Should be (perhaps) but clearly isn't. When you run it through a
standards body and/or obtain broad acceptance; great! Until then, it's
pipe dreaming.
