Like I said, this screws up the mail for the 99% of people who don't use
ADSP. since they can no longer respond directly to the authors of (some)
list mail.
No it doesn't. An essential part of the scheme was that the MLM should
provide a mechanism so that replies sent to the mutilated From: would get
delivered correctly (and for added safety the Reply-To would normally be
set too). So all users would be able to respond directly to authors as at
present, probably without even noticing that something lightly odd was
involved).
As I also noted, people who believe that they are so important that
it's essential for recipients to verify that mail is really from them
can use S/MIME, which is if anything more likely than DKIM to survive
list mangling.
That might be a fine thing, but you then have the problem of educating a
large number of people to do something they do not currently do (and
likely don't even know how to do).
