That to me says a purpose built computer, which both my desktop and steam deck sole purpose is to play games.
I don't need regular updates either, I need a stable OS. Most games are not on the bleeding edge of technology and need the latest Windows features, especially if those features are not back ported to Windows 10.
Again will point out that I am running this daily on my Steam Deck for gaming and have had zero issues with compatibility.
I mean there is some truth that it is missing stuff, I had to install some gaming libraries. But it just installed it when I missed it, it was easier than dealing with dependencies in some repo's I have worked with. And this was on a touch screen without a keyboard and mouse on my Steam Deck.
I am pretty sure anyone that has ever installed anything on Windows could figure out how it works.
Now the only catch is if certain things you install have to install enough things that you are suddenly back to a normal Windows installation (for example, it doesn't come with the Windows store but when I installed the Xbox app it relies on that). But that same catch exists for any debloat tool as well.
