ARC addreses the problem that mailing lists do a lousy job of spam filtering, A list that usually sends lovely clean mail sometimes doesn't, since a typical list forwards anything with a subscriber's address on the From line including spam from cleverish spammers who take pairs of from/to addresses from stolen mailboxes. ARC lets the recipient system look back and do what we might call retroactive filtering, using info about messages as they arrived at the previous forwarder. While it would be nice if lists did a better job of spam filtering, they don't, and ARC is a reasonable remedy for that.
I'll be eager to see the papers substantiating this. Until then I remain completely skeptical. It's an experimental RFC for a reason. Let's see the data.
I'd also like to see a paper substantiating your claim that mailing lists do a bad job of spam filtering. In my experience it is a non-problem.
