I apologize if this has been discussed before (I have about 1400
unread TLS mailing list messages in my queue), but it seems that
a simpler SCSV or extension could just ask the server to echo its
highest supported version:

    ClientHello w/SCSV    ----->
                          <-----    ServerHello w/version extension

Servers wouldn't have to change any logic or close the connection,
the client would make that call.
