-          This specification does not allow an origin access to sensors on a user’s device directly, but information exposed by sensors (e.g., the screen orientation angle) can be accessed indirectly.

+          The screen orientation type and angle of the device can be accessed with the API specified in this document,
+          and can be a potential fingerprinting vector. However using this information is very difficult compared to other fingerprinting information. 
+          Aggregating information derived from this API is not very helpful in fingerprinting. 
+          In particular the Device Orientation API provides a far more detailed version of the same information. 

By "Device Orientation API", do you mean the [DeviceOrientation Event Specification](https://w3c.github.io/deviceorientation/spec-source-orientation.html), or the [motion sensor specs](https://w3c.github.io/motion-sensors/)?
