Thinking some more, I believe that David Benjamin's "version based" solution does not actually prevent ossification. The middle boxes will be programmed with the seeds of version 1. They will try decrypt with V1, and if the result is not "version = version 1" they will just say "this is not QUIC" or otherwise drop the packet.
