Should DMARC-bis reference ARC? I don't know; can it? What I mean by that
is that some of us have an interest in DMARC-bis being published as
Standards track, and ARC is Experimental, and I don't fully understand the
rules regarding down-referencing (is that the right term?).
This would be fine:
"One possible mitigation to problem X is [ARC], which provides for a
mechanism to demonstrate 'chain-of-custody' of a message. However, use of
ARC is nascent, as is industry experience with it in connection with DMARC."
I'd insert a third paragraph in section 5.8, Policy Enforcement Considerations,
after the 2nd paragraph, which explains not to blindly reject. Let me try and
expand the text above:
One possible source of alternative knowledge is [ARC], which provides for
a mechanism to demonstrate 'chain-of-custody' of a message. However, use
of ARC requires extra care in understanding its implications, as industry
experience with it in connection with DMARC is still being gathered.
