ARC lets the recipient system look back and do what we might call

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.
People from Google have told me that is the specific reason that they
need all the complexity of ARC rather than just whitelisting mailing
lists. If you think they're lying, or you know more about their mail
stream than they do, not much we can do about that.
Then they should publish it since it's an IETF document it so everybody
can evaluate it. Otherwise it's just a private vanity project. I've seen
absolutely nothing to conclude it is not.
And impugning me about "lying" is an ad hominem and against NANOG's rules.
