Can Google stop add features that are already developed by 3rd-party apps?

I mean it's kinda annoying, especially if these features are already in PAID 3rd-party apps. Ex. I purchased an app called Settings Extented to add a row of quick settings on my Nexus 7 Android 4.1. Now 4.2 comes out with quick settings already built-in, my app purchase now seems useless. Also I am sure the same thing happens to Swype of Swift-key...
