Interesting question. Assuming the lists confirm subscriptions, which is
close to universal these days, what further benefit would DMARC provide?
You already know that the subscribers are who they say they are.
If there were an issue of bad guys faking subscriber addresses to sneak
mail into lists, it might be useful, but I've never seen that. What I
have seen is accounts taken over by crooks who then blast mail out to the
victim's entire address book, which happens to include the lists they
subscribe to. Not much DMARC can do there.
