Oh well. It is hardly the first time that consensus did not involve my
consent.

The current design has been in the draft since October, and we discussed
it on this list at great length.

I don't understand your point here, Doug. It seems more likely that a
subdomain of a subdomain should be following the latter subdomain's
policy by default, rather than the higher-level domain's. That is,
for a.b.c.d, "a" would be more likely to expect to follow "b" than
"c". Which means that th
I seem to have missed this redesign. I thought the plan had always been
to take the top-most policy not flagged as PSD=Y.Taking the first
policy found is less work, but it turns subdomain policies into
organizational domain policies. I expect that to be an unwanted surprise

I haven’t done extensive research but here is a live example where treewalk will cause a result change.

I don't find this to be a surprise.
I believe we discussed this specific type of case early in the tree walk
discussion. An early proposal was to walk up the tree to find the PSD and then
reverse back down the tree to find the org domain (PSD +1). This approach
would have provided an identi
The issue here, Tim, is that the current way of checking the PSL would send
you to the DMARC record for cuny.edu and p=none, while using the new tree
walk would send you to the DMARC record for bmcc.cuny.edu and p=quarantine.
In this case, it’s showing that the tree walk is the better mechanism,

I don't think this is a substantiative compatibility break that warrants a
version bump. A version bump effectively translates to 'this is a new protocol
with zero deployment', which is not what this group is charter

That means that everyone will have to publish two DMARC records, one
with v=1 and one with v=2. How long until it's safe not to publish the
v=1?

I recognize that the changes in DMARCbis without also changing v=2 are
possible and don't cause a security problem as ignoring "pct" when parsers
