Right, my current value of message-forward-ignored-headers is:
("^Content-Transfer-Encoding:" "^X-Gnus:" "^Received:"
"^Return-Path:" "^X-Original-To:" "^Delivered-To:"
"^X-Virus-Check-By:" "^Received-SPF:")
(i don't care to strip out DKIM-Signature headers because i see that as
part of the initial message injection into the SMTP system)

This all sounds like it would work, but it seems like a lot of trouble
compared to fixing a regression. this filtering worked just fine for
me before i upgraded to emacs 27.1.
I've filed a report about the regression with emacs upstream:
https://debbugs.gnu.org/45631
Thanks for helping me think through the details, Teemu.
