kazuho approved this pull request.

The text looks fine, and I think that the design change is also fine.

IIRC, current design allows a server to process a Initial packet with a token that it does not understand. I am not sure if that is good or bad, but at least it's slippery.

The proposed change enforces the use of a retry token for handling the payload, addressing this slipperiness (note: unverifiable new_token tokens can be ignored regardless of this PR).
