A message content type is one possibility, but other headers might also
be reasonable.

Shrug.  I wouldn't consider it to be silly for an MUA to apply those
tests to any message/rfc822 part, whether or not it came from a mailing
list.

If I do a forward-as-attachment to forward a message to you, it would be
good if you could independently verify that the forwarded message is
from who it says it is from.

Anyhow, it's clearly possible, probably with minimal standards for
message metadata.  The problem (after getting agreement on the metadata)
is getting an adequate number of MUAs to behave well with the wrapped
messages.
