It seems this will require changes to both ndn-cxx and NFD, since they each have their own Nack encoding mechanisms in their respective face systems. Is this correct?

So, if I'm understanding this issue correctly, the Interest-to-Nack matching function will need to be changed so that all five of the fields match, instead of just the first three as in the Interest-to-Interest matching function?

I'm uncertain about library behavior. You can check how Python library is doing things.
Forwarder behavior is answered in #5105-3.

At the NDN Platform Call on May 22, 2020, it was decided to revert this design decision and instead encode the entire original Interest in Nacks. Therefore, this change is not needed.
