Really? Can you clarify the meaning of the following passage? Because I 
can't read it in any way other than to contradict your assertion above:


    A server receiving a ClientHello and a client_version indicating
    (3,1) "TLS 1.0" or (3,2) "TLS 1.1" and any of the cipher suites from
    this document in ClientHello.cipher_suites can safely assume that the
    client supports TLS 1.2 and is willing to use it.
