I have to say, I completely forgot this was a feature for a while, but recently I was playing Kingdom Hearts: Melody of Memory on my Switch Lite. The primary function of hitting notes in this game is mapped to A, L, and R. The L and R buttons on the Switch Lite are pretty small and not very comfortable to hit in quick succession. But I suddenly remembered that the console had gotten button remapping a couple years back, so I swapped L with ZL and R with ZR and this problem went away entirely. The ZL and ZR buttons are much larger and designed in a way that makes hitting them in quick succession much, much more comfortable. I don't know why Square Enix went with mapping this to L and R other than that they assumed most people would be playing with a Pro controller or on PS4, but either way it was a relatively painless fix and if I ever start my Switch up with another game it asks if I want to reset button mapping. It's a nice feature, glad they added it.
