Thanks for this.
Do you have any insight into which sources of DOM sensor data {devicetemperature, devicepressure, devicehumidity, devicelight, devicenoise, deviceproximity} are available on which hardware devices, operating systems, etc.? Someone with substantial traffic must also be sampling this, right?
