There is no guarantee of that. If my bank says reject that mail, I want
my provider to reject that mail, period. No amount of ARC shenanigans
should change that policy.
OK, ARC doesn't do that. This does not mean that ARC is broken, only
that you appear to have different policy priorities than other people.
As you know, DMARC has never obliged recipients to follow senders'
policies so this is nothing new.
If ARC is advocating for a bypass of p=reject that introduces a new
state. If my policy is reject, I want you to reject the mail. If I want
you to reject the mail unless you think it has come from an acceptable
place with receipts, then you need a new policy tag like
reject-except-valid-arc.
