Microsoft tried to do the same thing on the Desktop side too, but on the desktop they were forced to keep the backwards compatibility in place so it didn't finish off the platform the way it did on the Phone side.

Amusingly Microsoft is still trying to make the walled garden happen. Lots of cheap Windows laptops and Desktops ship in what is called "Windows S" mode where only Microsoft Store apps are allowed to run. But again because PC owners don't abide that kind of bullcrap they also have to supply a way to tear down the walls (it's surprisingly easy, albeit permanent: just download and run a free app from the Windows store) if you want to use the machine in a normal way.
