I find the idea of extending rfc6091 with a new certificate type
for raw keys more appealing that a completely new TLS extension.

I also prefer the server key to part of the full TLS handshake, so that
the situation "client doesn't trust server key" or "client expected
different server key" can be reliably distinguished from other reasons
of a Finished message verification failure.
