Windows is extremely modular, even if it doesn't look like it to the end user. A lot of components can be disabled through unattended install process. At least since Vista there's a concept of Core with layers of stuff on top that can be enabled or disabled during the build process. The only issue I see here is: why would anyone pay for a Windows license that doesn't have all of the basic Windows features like printer access? Special N, K, and KN editions were just a cost to develop and test with no benefit to users.
Many people who wouldn't touch a gaming PC with a stick have bought the Steam Deck because they think it's a console, and it acts as such.
That would unite a lot of people, both PC gamers who could finally have some target specs, for example that in a game you get Xboy Medium, Xboy High, etc, to choose from, and console players very simple options that are transparent to them.
And it would help to sell more Windows, which is what is underneath.
Then, if you want productivity, you can run full-fledged Windows in sandbox mode in a VM and there you can use the Print xD service, and everything else you want, and more, also it should be shown in a transparent non intrusive manner for those who want to play and make the most of their PC's resources.
If they do it right, they would have a winner on their hands, but they have to show tangible advantages, or benchmarks - a vanilla Windows 11 vs Windows 11 Gaming - that show how much performance and efficiency you gain by removing things that are not necessary for games, thus the product doesn't fall in the "it doesn't add value to a PC gamer" category, 'cos if you don't do it right it could be in no one's land, nor cattered for console gamer nor for PC gamers, because they think that what they have is fine.
But if you get it right it can make gaming a breeze universally.
Also, the benchmarks could be very interesting to see, maybe most traditional PC gamers and people would migrate to a Windows gaming platform if the performance gains are tangible and know they won't lose the productivity when they need it.
