I'm waiting to see how that one stabilizes before commenting. Ultimately, I
think such techniques will be handled much better by DANE.

You want the client to somehow make its options read-only? What if they got
locked down in a less than optimal manner? What if they were locked down
such that when a new security feature was available, the user couldn't then
take advantage of it.
This also requires us to standardize the meaning of lockdown, and also
standardize the options we want to be included. I really don't think this
one will fly.

How does the server know if the client is lying or not?
As an aside, channel binding obviates the need for at least the former,
since it ties in authentication with the TLS channel in such a ways that
there can't be a MITM between the client and server without the
authentication being broken anyway.
