Suppose we made the mailing list software take the contents of the

DMARC people would want, right?

Except then, a couple of years later, because users might actually
want to find the message that was written by "Brian Carpenter", or
<snip>

Worse than that.  That would any authentication back to the original author.

Personally, on my incoming mail, I really don't care if a message passed through a mailing list or not - if it says it's From: <foo>, what I really care about is that it really is from <foo> and that it's the message that <foo> originally sent (modulo things like subject tags, and list headers/footers) -- if some random mail list wants to forward the mail to me, and it comes through intact - do I really care about the legitimacy of the list server (other than not wanting it to become a spam or attack vector)?

Not sure that's completely clear.
