Re: [DNSOP] Second Working Group Last Call for draft-ietf-dnsop-extended-error

I like this idea, and am aware of at least two other proposals that would (or would have) benefited from a new OPT record [EDNS header flag bit] to communicate "incomplete response" as distinct from "truncated response" (the latter encouraging retry over a transport supporting larger messages,

Re: [DNSOP] Second Working Group Last Call for draft-ietf-dnsop-extended-error

extended codes are pretty important in the DoH space - which doesn't require library intermediaries. IIRC the very important use case was disambiguating DNSSEC validation errors from other errors (as retry behavior could very well be different). So this has been eagerly anticipated. On Tue, Oct 22

All The second WGLC period ended, and I needed a bit of time to go over all the comments and make sure they were all addressed, and that appears to be true. The only thing I see are some comments were raised after the -12 version. They've been addressed and can be updated on its way to IETF LC.
