I think that irrespective of its status, if ARC had been able to deliver
results like what we thought might be possible, its adoption would have
been far more solid. But it didn't, and so it wasn't.
That is, I don't think it would've been any better had this WG or some
other taken it all the way to Proposed Standard status before re-tackling
DMARC.
This is a purely academic topic. We can't calculate what developments would
have occurred if ARC had been better understood or specified.
Now we can confront demoting ARC against an actual proposal to clarify it and
put it in use. A showdown where we can weight pros and cons of the two
alternative ways. And an opportunity to resume the proposals that had been
postponed.
NEW:
Accordingly, DMARC is being rechartered to investigate the current status of
deployment and the possible potential, ultimately publishing a document that
either moves RFC 8617 to historical/obsolete status, or corrects its usage
model so that ARC can effectively regain its intended role.
I'd support this if I thought there might be something in ARC worth
developing, but I haven't seen any evidence of such interest or momentum.
Put another way, if the charter said this, who would put in work on the
latter branch?
I think we can only find out if there's interest if we write this in the
charter. It would give us more leeway, and the WG future might be a little
longer than a quick approval of a demotion. Not such a disfiguring option,
considering the WG's is already over a decade old...
