A privacy policy can help confirm the absence of data collection as much as it can also be used to explain how collected data (if any) is used. If anything it's a helpful change, as it provides a standardized way for apps to confirm they collect no data.
Any app submitted to the iOS store has the same requirement to provide a privacy policy too, and again even if no data is collected.
General note for app developers: Try to think of the worst, most sociopathic things you could do with your app's level of access. Then reassure your customers by using your privacy policy to create a legal obligation never to do the things which would enable the ability to do those things.
If you don't tell me you're not doing it (in a way that I can clearly sue you if you do), I have to assume that you are doing the absolute worst things your app is technically capable of doing with the data it has access to. That's just the way the world works these days.
