I think I agree with @fergald's original point. If we make the assumption that it is difficult to reverse engineer the low-level sensor values from a high-level sensor values then the current permission and feature policy design doesn't make sense. A model which gives both users and developers the ability to make meaningful choices about the data being exposed should provide a strict ordering based on the sensitivity of the data. For example, the set of `raw-accelerometer` and `raw-gyroscope` permissions may imply the `relative-orientation` permission but not the other way around. On the other hand I believe the point that @snyderp is making is that even the high-level sensor data is sufficient for fingerprinting, which renders the idea of this graduated permission model moot. In that case I believe, as discussed on w3c/deviceorientation#85, that the best solution is to find a mitigation through precision reduction or noise injection which removes fingerprintable behavior while not significantly changing the behavior of the sensor. -- GitHub Notification of comment by reillyeon Please view or discuss this issue at https://github.com/w3c/sensors/issues/399#issuecomment-555726838 using your GitHub account
