I like the simplicity of this proposal. The main downside I see is that it's possible for a server to never send HANDSHAKE_DONE. We could solve that however, by saying:
- the server MUST send HANDSHAKE_DONE in all its 1-RTT packets once its handshake is complete and until one of them is ACKed
- if the client receives an ACK for a 1-RTT packet it sent and has not seen HANDSHAKE_DONE, it MUST close the connection with a PROTOCOL_VIOLATION
