> Note that this isn't completely trivial to implement. If a servers responds to packet 1 with Retry, it has to ignore packet 0 if it arrives with no token (or a NEW_TOKEN token). That's already a requirement

How would the server know to ignore packet 0 in a *Stateless* Retry?  I believe it would respond with another Retry packet instead.
