FWIW, I think I'd notice if mail clients were using Return-Path.  I'd
see it in the sourceware log and, if it is occurring, it is not
occurring with enough regularity for me to notice it.

People misuing the "Sender:" field, OTOH, happens almost daily.  It
results in people sending email to gcc and gcc-owner.  The end result of
that is a little self-contained discussion amongst all of the people
cc'ed since I don't allow email cc'ed to *-owner to make it to a mailing
list.  At one point that was a sign of spam.  Nowadays it just is a sign
of a misconfigured mail client intent on spamming postmaster.
