I missed this response, sorry!

I think it's important that the spec leave us the flexibility of doing
mixed content checks based upon data that we can only know after connecting
to a server and poking at a handshake. It's certainly the case that we have
concrete plans (and, I think, implementation (Ryan?)) to do this in Chrome.
I'd prefer to leave the concept in the spec for that reason.

Another option that I could live with would be to drop the concept from the
spec explicitly, and to simply rely on Fetch's "HTTPS State
<https://fetch.spec.whatwg.org/#concept-response-https-state>" in
This has the practical effect of making it possible for Chrome to continue
our SHA-1 deprecation plans, simply deferring the conversation around
"deprecation" from MIX to Fetch. I'm not sure that's an improvement. WDYT,
Brian and Anne?
