Currently, [the Path Validation Responses subsection](https://tools.ietf.org/html/draft-ietf-quic-transport-29#section-8.4) does not specify which path a PATH_RESPONSE needs to be sent over. That was somewhat surprising to me, as I had expected it to be scoped to the path that PATH_CHALLENGE was received on. If it isn't, could we add a sentence to the Path Validation Responses subsection to explicitly state that a PATH_RESPONSE is not scoped to a given path (and ideally explaining why it isn't)?
