The term "non-NIST" is predictive, and the crypto community kinda sucks at predictions. We have no idea what NIST will do in the future if a bunch of IETF WGs adopt specific elliptic curves that are not P256/P384. Unfortunately, I suspect current NIST folks also have no idea what NIST will do in that case either. In the past, NIST has sometimes (but not always) responded to pressure from the real world about crypto algorithms and modes; let's hope for the best here.
