1. I think this is OK as long as we limit how many path responses we send immediately?  Realistically, it's not that different from a generate_204, but it's something to be aware of.
2. I think we need to add a whole section on paths and connection migration in recovery. See #2684   I can do that in this PR if people want? 
3. #2367 decreases the value of this, since you may only see one half of the path.  It might still be better than nothing?  Initial RTT doesn't need to be correct, but getting it within a factor of 2 is helpful.
