Back to the subject topic, based on what one of those 800 pound G. wrote, it 
turns out that rejecting mail where multiple authorship is expressed by 
multiple From: mailboxes was introduced as a requirement to implement RFC 7489. 
  I didn't notice it until a few days ago.

These days, both RFC 7489 and RFC 5322 are being rewritten.  Yet, the sentiment 
of the community who rewrites them seems to be that since that feature is 
seldom used, it is a waste of time to consider it.  Such a schizophrenic stance 
leads to inconsistent standards.
