Yes, that fully addresses my concern. Thanks!

Hi Ted,
Doesn't this section of RFC 9460 address this case and say what you are
recommending:

Okay, I think I see the disconnect, maybe. The issue I'm pointing to is
that you may or may not be doing DNSSEC validation. And you may or may not
be /able/ to do DNSSEC validation if the infrastructure breaks it
accidentally or deliberately.

I don't think it relates to DNSSEC. You can fail at DNS (DNSSEC failure) or
you can fail during ECH (unless you want to use non-ECH, which is not ECH,
and not part of this draft).
It makes sense to me: one can reject a request unless the requirements
embedded in the SVCB are met (the server choose
I'm not telling you that you have to require DNSSEC. I'm saying the

think EKR got the point, so maybe go with his approach?

It's a policy choice, though, right? I think ekr hinted at this issue as
well.
It's that one might also view requests that reveal the SNI as insecure. If
that's the case, DNSSEC doesn't help. There will certainly be a transition
period where that will be impractical for many servers. I think these
It looks like if you can't get the SCVB you're going to fail insecure, so
being able to use DNSSEC to prevent that for signed domains seems
worthwhile.

That seems okay. Would be good to document in the security considerations.

In a key agreement algorithm, both parties contribute to the shared
secret. With a KEM, only one party generates the the shared secreat value.
This is not generally accurate with the KEM schemes under consideration for
ado

Could you explain more about this part? I think DNSSEC doesn't add much

This is a DNS Directorate review for draft-ietf-tls-svcb-ech-01.
Section 4.1 advises disabling fallback, but does not talk about DNSSEC, which
is surprising given that the draft proposes privacy properties for SVCB
responses containing ECH data. I w
Hi! I am going to kick off some early reviews from the DNS and HTTP
directorates to see if we get anything back.

I am fine with putting a more inclusive name on the existing range.
