Well, sure. What do you think mailing list MIME digests are?
I assume that you're referring to multipart/digest.
The disadvantage is that a lot of mail systems, particularly popular
webmail, deal poorly with embedded messages.
Agreed.
I'd be worried that some (web) MUAs would deal with multipart/digest
worse than they deal with message/rfc822 contained in the former.
Especially with the comment that someone made about inline vs attachment
disposition of the message/rfc822 MIME parts.
When the IETF was trying to figure out the least bad way to deal with
DMARC list damage I mocked up some possibilities including a couple of
ways to wrap messages as attachments. We found that unwrapping and
replying to them worked poorly, so we decided on per-user From
rewrites (my dmarc.fail hack) instead.
Yep.
