Popularized by Usenet?  Huh?  Precedence has never been a Usenet header
that I've ever seen.

The oldest use of precedence that I'm aware of is that Precedence: junk
has been in the headers generated by the old-style Unix vacation program
for eons, and sendmail.cf had handling of a few different types of
precedence headers and they had some effect on queue prioritization.
