If you turn the complexity curve of debloating and custom Windows ROMs about 90 degrees, it's the same as the backwards bend Windows users are doing to avoid jumping to something easier like Linux Mint.
Not to mention any later compatibility issues you may need to diagnose, particularly with gaming. Not everything works with Proton and there are other stores than just Steam.
A debloated Windows is still Windows. Bundle this with a "use these debloat settings for gaming" and it could be just clicking a couple of buttons for the majority of users.
