Its definitely a peripheral i dont see how you can argue otherwise. This isnt an opinion it either is or isn't a peripheral. I think people fail to understand this and it causes unnecessary arguments.
Take out the Kinect and the X1 works perfectly without it. The UI works fine and MOST importantly the games work without it.
Take away the traditional controller and you cant do jack shit with your X1.
Now if MS took away your ability to control the UI with the traditional controller and made it mandatory to use the Kinect then yes its an intergral part of the system but they havent done that and they never will.
The wii remote is good example of not being a peripheral where the move is...yet they do exactly the same thing...
