If you're suggesting that ARC is only useful when you already trust the forwarding party, and if you trust the forwarding party, why do you need ARC, yeah, that's been pointed out before. The best explanation I've seen was from someone at Google who said that they often see well behaved lists suddenly start to send spam when a spambot happens to send mail that fakes a subscriber's return address. ARC would make it somewhat easier to tell when that happens.
