Comment (by isis):

 I had a discussion with Ian at RWC2018 about the changes, and we have a
 meeting scheduled for later this week to discuss (and hopefully come to
 some agreement on) them. Notes and takeaways from the meeting will be
 forthcoming.

 As part of #24985, we'll need to implement ​prop#269. This should probably
 be in two parts:

 1) Implement a new module which, given function pointers to two
 handshakes (one classic and the other post-quantum secure) which follow
 some prescribed API, compose the handshakes together to produce a final
 shared secret
 2) Implement "hybrid null" (as it's called in the proposal), which
 here I'm calling "ntor2"

 This ticket is about part 2. It ultimately depends upon #24986 and #24987
 as well, although it can be done (and even rolled out into production, if
 we chose to do so) before either are finished.
