The Wii U Gamepad functions are integrated throughout the console. As much as many users here wish to not admit it, the Gamepad isn't an optional add on and was intended for the console's UI use throughout it's development.
The Kinect 2.0 is more of a glaring add on and shouldn't have to be shoe-horned it. The problem also stems from it's an upgrade from what was ALREADY established as an add on. The Gamepad, however, debuted on the Wii U.
