(no hats) This will expose a new property of hardware, so there should be a fingerprinting note, no? I think Gamepad details are gated on user input or user interaction in some way?

@tomrittervg thanks for pointing this out. I have added a "privacy considerations" section to the explainer. Regarding your question, yes. You are correct. navigator.getGamepads method returns an empty list before a gamepad user gesture has been detected. Only after that websites will be able to query for the gamepad's haptic capabilities.
