>    I propose we just avoid this situation entirely by making NTS a
    mandatory part of v5. NTPv5 gets a separate NTS Next Protocol code
    from NTPv4, so version negotiation happens during NTS-KE. And then no
    correct client will ever emit a v5 time packet without already knowing
    that the server supports v5.
  
That makes sense.  I support this.
