The intent here was that either (a) you only ever have a singe CC context and you reset it for each path, or (b) you have a CC context for each path, in which case each context is strongly tied to a path and you don&#39;t need to reset anything (except when it&#39;s been a while and the previous values may no longer be valid, etc.). We require that everyone does at least (a), while not preventing folks who want to do extra work for a potential performance gain from doing (b).

Packets *can* contribute to the CC/RTT estimation for the old path if it&#39;s still around and you&#39;re willing to maintain that state, which is why this (mistakenly) was a SHOULD.

Closes #2909.
