I've seen multiple authors (more than one address in the From
header field) in NetNews articles (e.g. for posted FAQs).
Please note that "multiple Froms" is a shorthand for more than
one author, "multiple From header fields" would be erroneous.
Nobody proposed to deprecate or remove "multiple authors" for
2822upd, it's a valid option, with a mandatory Sender address.
And the Sender address is not necessarily the same as one of
the author addresses.
My proposal to simplify at least "multiple Resent-From" (with
its mandatory Resent-Sender) into a single Resent-From for
2822upd was more or less unanimously rejected on the 822 list.
Dave's proposal to get rid of Resent-* altogether also didn't
make it, some folks really like the Resent-From email feature.

Just because we don't see it often doesn't mean that it's never
used, it could be even essential for something we've never heard
of before. It's how email works, and if SSP doesn't agree with
these 2822upd features it has a serious problem.
I've used From <> Sender (with different domains) in many cases,
any SSP claiming that I can't do this would be arguably broken.
