Greg, this was all done with deep involvement from the TLS WG; Eric was chair at the time, and now the document editor for 1.3.

There may be some mitigations we can introduce to make this easier for you. Dropping 9.2.2 isnít on the table here ó itís been discussed for quite some time, with input from TLS and SECAREA, and has strong support. 

One thing that Iíve heard is requiring clients to offer the ďgoodĒ suites first, to promote interop. Does anyone see a downside to doing that?

The other is making all of 9.2.2 (and maybe 9.2.1) specific to TLS 1.2; i.e., to let TLS 1.3 and beyond control their own destiny.
