I can understand that disabling permissions the app expects will fail, but faking the service the app expects permission for sounds like something that should work, and would be very valuable.
Yes, definitely. XPrivacy can fake data, so that works even better than AppOps, but is harder to set up.
I also miss the possibility to give slightly fuzzed/offset values for certain things, like GPS granularity (Do you need to know my exact location, or just my country?) There's however an eternal struggle between the API devs wanting to make the permission system simpler, and the APP devs wanting it smarter and more refined.
