C++/WinRT also does COM anyway,

Microsoft Game Development Kit makes it clear that for AAA titles, the Win32 + GDK model is the future, while WinRT APIs are being deprecated, and only community support is planned for UWP, not from Microft XBox teams.

So one just needs to read between the lines, combine it with years of experience with previous technology reboots from Microsoft, and it is relatively clear where they are heading with Windows 11.
Naturaly when playing futurology games there is always a possibility of being wrong.
But this sounds like a good thing to me overall. I was never a fan of UWP as most of the apps were too tablet focused. The same issue I have with Mac Catalyst apps. Too dumbed down and basic. I know it's not technically necessary to do so, but these unified platforms seem to stimulate that kind of app. I was also very happy to see that live tiles are going away (It always takes some time for me to rid the start menu of them).
If Microsoft would adopt a more privacy friendly stance e.g. no telemetry or MS accounts required at all, I'd actually consider using it again for more purposes privately.
