Martin didn't want to allow for ACK of handshake stopping the anti-amplification retransmissions, which I think is fine, though a bit overly strict.  So all of this is within the "if (endpoint is client without 1-RTT keys)" conditional, which is our proxy for: Should we keep trying to prevent a deadlock?

To be clear on what I'm suggesting:

else if (endpoint is client without 1-RTT keys):
  // The client must continue sending packets until it's
  // sure the server has validated the path.
  if (has Handshake keys):
