Re: [dmarc-ietf] WGLC review of draft-ietf-dmarc-dmarcbis-30

I’m saying, as an individual, that there was a thread where we discussed a
new N for the tree walk. There was appetite, but no new N was settled on.

Given that prior appetite but no conclusion, I believe as part of WGLC we
should choose that N. I proposed what I think would work. John Levine
chimed in that he thought that was reasonable.

Do you have operational experience as a report consumer that this would be
a mistake and more complicated organizations should not be able to receive
reports?
