Re: [generic-sensor] - Sensors API - core

Hi.
well, that's a good point, indeed!
But

window.addEventListener('deviceorientation', ... )  // depends on window.
navigator.battery.level // depends on navigator
window.addEventListener('deviceproximity', ... ) // depends on window
navigator.getUserMedia( ... ) // depends on navigator
window.addEventListener('devicelight', ... ) // depends on window
navigator.geolocation.getCurrentPosition( ... ) // depends on navigator

We got the same problem.
Maybe the global `Sensors` is indeed the best option.
