Right? It was clearly written in a way to convince most people not to use it but it's a perfectly viable Windows installation for most people.
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.
