The only "big" change that came about so far has been the HTC Vive controllers (which are amazing). The ridiculously simple solution for WebVR was to add support for them to the Gamepad API https://developer.mozilla.org/en-US/docs/Web/API/Gamepad_API/Using_the_Gamepad_API https://developer.mozilla.org/en-US/docs/Web/API/Gamepad_API... This is a great example of how the hardware can differ but the software can be the same. Both Oculus and Vive work on WebVR, including the Vive controllers. Nobody had to throw away everything and start over just because of a hardware innovation. If we start seeing special SDKs for each platform, this benefit goes away.
