It's an interesting state that you can force someone to unlock their phone with biometrics, but you can't force them to reveal a pin.

Anecdotally, I have been to the US a few times in the past year, and seen no change myself - where are you going and why? Thanks have a good trip. It was for short business trips, and I'm white with a number of documented entries/departures, so my experience might be very different from the next person though.
