By “obsolete keyex draft” you mean expired, right?

I am in favor of MUST NOT have a certificate with DH keys.  So yes to 1. I think #2 is unenforceable/undetectable, but would be happy to be convinced otherwise.  So I’m unsure about #2.

But yes, let’s adopt and merge in the expired keyex draft and then argue over it.
