I agree that it’s stupid there’s only a few buttons to interact with, yet we can’t use them for the mouse. But it’s even more of a pain if you have an AZERTY keyboard, or play left-handed like I do. I have to use the arrow keys in games, and since I can’t change the WASD keys that are hard-coded, it means I can’t play the game I paid for. They don’t seem bothered to patch it, either.
