npdoty has just submitted a new pull request for https://github.com/w3c/deviceorientation:

== limit precision to mitigate sensor calibration fingerprinting ==
require no more precise than 0.1 degrees, 0.1 degrees per second, 0.1 meters per second squared

updated examples to keep precision limits
updated privacy considerations to note sensor calibration as threat
added reference to sensorid paper

draft attempt to address w3c/deviceorientation#85
Feel free to comment or edit to match WG style etc. May also need updates to web platform tests to confirm that sensors do not return more precise values.
