For better or worse, we've got a perfectly good, standard, way
of doing that when the list is to be treated as the sender.
That would be to ask developers of list software to use
Resent-From. It has its own set of issues and the various bits
of software that try to tie keys and DNS records to mail
originators would need to be upgraded to understand the
semantics of "Resent-*" (and, btw, Sender) fields, but it would
conform to the standards, not loose information, and not closely
resemble a cheap hack.
