From August 31, the type of apps in Google’s crosshairs will include those “that are static without app-specific functionalities, for example, text only or PDF file apps, apps with very little content and that do not provide an engaging user experience, for example, single wallpaper apps, and apps that are designed to do nothing or have no function.”

I guess they want to get rid of noise (1,000 different apps who do exactly the same, and my-first-app tutorial apps), as well as apps made in bulk to make a malicious app developer seem more respectable, but I feel like a bunch of useful minimalistic apps will get lost too.
