First, the MLM side of this proposal is exactly what the Mailman "Wrap
Message" action does. It wraps the original message, unchanged except
for content filtering as a message/rfc822 part in an outer message. List
headers and footers if any are added as separate parts in the outer
message and all subject prefixing, From: header munging addition of
List-* headers etc is done to the outer message.

This action is almost universally ignored in favor of Munge From because
of MUA deficiencies. There are MUAs that will render such a message in a
highly readable manner, but there are others, particularly mobile device
clients, that make it difficult to impossible to view the wrapped message.

If Thunderbird can do a reasonable job of rendering such a message, and
it does, there's little if any excuse for other MUAs to not do so. Even
Yahoo web mail, which I just tried, does OK after I click "Show original
message".

But, when this was initially implemented, I tried using Wrap Message on
my bicycling club's lists, and I received many complaints so I went to
Munge From.
