I suppose you could encode the list name into the

you've subscribed to, but in practice I suspect that it makes more
sense for the MUA to remember the lists and addresses along with other
info like how to unsubscribe.
the purpose of batv is to record some state into the return address, so the
origination site does not have to maintain a list of sent messages.
the purpose of the current proposal is the same thing, albeit for a different
bit of state, namely providing a means by which the mailing list can 'prove'
that the addressee did subscribe.
so it seems a reasonable idea, although the fact that it requires changing
mailing lists (to accept a From field that differs from the subscription
address) is a non-trivial hurdle.
