[Joe] I mean this draft - draft-aviram-tls-deprecate-obsolete-kex-00 (the
subject of the other adoption call).  There were several comments that we
should merge the two drafts.  Since draft-bartle-tls-deprecate-ffdh-00 and
the expired draft-bartle-tls-deprecate-ffdhe-00 are similar I would expect
we would merge content from draft-bartle-tls-deprecate-ffdh-00 into
draft-aviram-tls-deprecate-obsolete-kex-00
with perhaps some addition text on certificates with static keys.
