You can use debloated W10 on a separate SSD without internet, for all those Office and game needs. W10 is easy to work with and is safe. That said, I doubt it will be easy to debloat W11, and beyond W11 it might start to become almost impossible with tactics like server side activation and "approved hardware" schemes like Apple does. Time will tell.
I doubt many people will be willing to de-bloat their WIndows install, because there is a lot of overlap between the type of person that would be willing to go through all the hurdles of de-bloating, and the type of person that is already on Linux.
AME Project is excellent for easy debloating and demalwareing of Windows 10. Windows 11 is constantly being worked on as new crap features show their ugly butt heads. I use both AME10 and Debian, so I get the best of both worlds.
