SGTM.  Doesn't say how to check, but I'm not sure that there is any
simple advice you could give there.

> 2) draft-ietf-tls-tls13 will indicate cipher suites that are recommended for TLS1.3; remember the negotiation mechanism is different now so we’re using the same registry but the values are in the new range.  It seems like we still need to populate the recommended column for pre-1.3 from -14 A.4?

I think that TLS 1.3 should just register the small set of cipher
suites that it does and this doc can take on the other things.  What
was in -14 seems about right.
