I was also pretty disappointed to see that when you send a
trusted_ca_keys: pre_agreed value, that this is totally ignored on
servers, including openssl.org. I have a rough patch for openssl I used
for testing, but not one that takes any of the other RFC 6066 options (yet)

In fact, if I understood the versioning right, basically no one is
running TLS v1.2 yet, and the comments in the openssl 1.0.1 snapshot
suggested it had only partially started on TLs v1.1.

I did not expect this backlog on the TLS implementations.
