Maybe, but you haven't found it. To resolve your query, simply fudge the locations by 50-200m in random directions. You'll still get good local results and won't pin the exact room or house down with needlessly accurate location data. Amazon can keep that data of course, it just need not be shown to human reviewers.

Edit: I'm "posting too fast" and so cannot reply to the Uber comment below. I'll say, I still don't understand how human reviewers would need your address or GPS coords to improve their service after you get an Uber. How would they even verify the Uber came to the right place, they don't have the verification info there.

I just don't see this as a valid use case at all.
