Since UWP ONLY run on Windows 10 devices, it is a Windows 10 feature. It is also a forced feature if you plan on playing any Microsoft game on PC. It's very much a Windows 10 issue.
Not exactly, UWP apps run on Windows 8/8.1 as well. This one in particular requires Windows 10 because of DX12.
But the shortcomings of UWP are problems with the app platform, it's not the fault of the operating system itself.
