I still agree with Trent.  Seems to me those who lean “historic” have made objections clear, and shared their rationale.  Maybe it’s just not a hill to die on, or perhaps they feel their prior notes are sufficient?

P1: While others have found value in ARC, I found the opposite due to some of the points that the proposed document mentions in 3.1.   Should we examine each of those bullets for accuracy?  Have we sufficiently addressed that section?
P2: I’d rather see those who have the ability to do so work toward DKIM2, either (IETF) design or deployment.   If P1 suggests there is no/limited value in ARC (as RFC8617 is written), why wait for DKIM2 to note it as “historic”?

I think it's curious that consensus appears to have swung towards "do nothing" when, during chartering (and thus the reason we're still here), consensus was clearly "Trent's right, we should do this".  I can't tell why it changed in the interim.
