Right --- that is often confused so I wanted to clarify.

Yep, I am afraid so.  tls-unique seems technically superior, but I guess
not operationally superior, e.g., Java can't access the TLS shared
secret.  Supporting both causes the kind of channel binding mode
confusion that we have been dealing with, and the new security trend is
not to support too many options because their interaction is often
surprising, and insecure.
