HSTS is a single bit for a policy that browsers work hard to ensure (TLS certs for all)

No sensible browser (or other client) would want to enforce HSTS-PQ unless it was sure the same was true. That might mean ignoring expiry times above 1 / 7 / 30 / 180 days.

i disagree with the assumptions and causes stephen and ekr describe. If the chairs and new AD ensure people _can_ discuss on the list then based on adoption analyses, the group of \"yes with updated text\" would be rough consensus.
\n(again the problem is the voices of people responding to this who want to discuss text and only want to restate their \"no\")

I think the trend is that more and more people are showing reservations on the draft, rather than the other way around.

I do think that it's funny that we continuously have this challenge with migration in protocol design.

This PQ TOFU thing seems to assume that someone has mega-qubit CRQCs running at fast clock speeds, operationally linked to active MITM attacks, but we are still pretending ECDSA is safe. This seems like a strange set of assumptions.

\n

Where is the assumption that ECDSA is safe?

\n
\n

The client (or server) is still willing to negotiate ECDSA.

Ah. Right. I agree. I tried pointing out a related thought on list.

I think my point is just that \"HSTS\" and \"HPKP\" can be used as shorthands for different properties and trying to debate which it is in the abstract is just going to get confusing. :-)

I think the potential idea here is that highsecurity.com does this today when ECDSA is secure and then it's safe in the future when a CRQC exists

\n
\n

Today, there is no CRQC so MLDSA is irrelevant. Someday, CRQC will exist and ECDSA will be unsafe. There is no obvious middle ground when it makes sense for both algorithms to be deployed. The right answer is to switch to ML-DSA and turn off ECDSA well before we get to megaqubit CRQCs, and we should have plenty of warning for that.

I'm not sure that holds. HSTS seems like a better analogy: here, as there, there is an expectation that most clients have the necessary machinery to handle the handshake from the committed state.

@Benjamin Schwartz There's a few degrees of turning off ML-DSA. Happily, turning off ML-DSA for CAs is sufficient to get us downgrade protection.

HPKP commits to a specific set of keys, which is very different. So there is a distinction.

Abstractly true, but critically, the HPKP policy is determined by the client not the server :-)
