Detecting fake GPS used to be possible in SDK36, not anymore

There used to be LocationData.mocked property (in SDK36), which was true when GPS was being faked.

Now (SDK 39, 40) this property is gone, but I still see that in some cases it is set in the .java code here expo/ at master · expo/expo · GitHub

Does someone have any info if it is still possible to access it somehow in RN code with the latest SDKs?
