The Gamepad Extensions flag was originally added for issue 628417 . Most of the features were only useful with WebVR, and those are obsoleted by WebXR's input solution. The `touched` attributed was added to the main Gamepad spec and is now enabled by default ( issue 830140 ).
Thus, there is no reason for this separate flag. We can move the WebVR-specific extensions to be controlled by the WebVR flag. Other browsers shipped these extensions along with WebVR, so there isn't much point in keeping them separate, and there isn't a risk of committing to these extensions since we are not going to ship WebVR.
