Windows 8 and UWP weren't ever popular, but Microsoft is having a little more success parcelling up UWP:

* .appx became .msix; the latter also works for Win32 apps

* UWP XAML/GUI evolved into WinUI, v3 of which doesn't target UWP

* Win32 app isolation—this news—grew out of AppContainers, which were used by UWP apps

That said, what's new here? You could package (.msix) Win32 apps with partial trust, IIRC. Does this remove the need for packaging?

The new stuff are basically new package (msix) capabilities that trigger new codepaths in classical Win32 APIs. Microsoft's previous app sandbox required the use of WinRT APIs that not many people have adopted.
