I don't really see it as a separate mechanism, it just omits the bytes which
are redundant. The TLS 1.3 is a separate mechanism, and TLS 1.3 is not final
yet. While I'd prefer to see the draft published than not, I wouldn't like to
use an experimental mechanism, and my preference would be to use the current
mechanism without the redundant bytes.
