"There's no arguing with taste", but as a data point I have no problem
with multipart/mixed with only one part.

How about multipart/alternative:

    message header
    multipart/alternative

        part header
        message/rfc822        # original message in all its glory

        part header
        <traditional cooked list message>

AFAICS this is completely unnecessary?

    message header
    Content-Type: message/rfc822

        original message header
        original message body        # or cooked if you prefer

Then amend the existing MIME RFCs to say that MUAs SHOULD (MAY?)
simply display the original message in some appropriate way.  No?
