Except that DKIM2 will let recipients reliably look back through the changes that forwarders make. Even if I have never seen mail from a forwarder, if I can examine the changes and see that they look like a mailing list, e.g., a subject tag amd a short message footer, I'd deliver it if I would have delivered the original version. While I don't expect recipients to try and figure out arbitrarily complex changes, I do expect that most legitimate changes will be simple, and some heuristics to recognize common changes will let most list mail through without having to know who you trust. I also expect some cooperation from list software authors to help make the changes more consistent. It's not a 100% solution, but nothing is, and this is a lot better than ARC. If it were practical to set up shared lists of trusted forwarders. it would have happened in the 10 years since the ARC draft was published.
