Thanks; I didn't see this bug report before I fixed the text/plain thing
in a different way.  (So I think s/mime should basically work again now
in Emacs 27.)

This sounds like a good addition to me, and would like to apply the
patch to Emacs 28.  It's a large patch, though, and you don't seem to
have copyright FSF assignment on file -- is that correct?  If it is,
would you be willing to sign such paperwork, and we can then apply the
patch?
