GNOME unfortunately does not have enough maintainers to do this. If you'd like to help out, please contribute, or help direct some others to do so. That might mean helping to maintain some extensions that you're using. If you don't want to help, and you want to use KDE, that's understandable too -- but please understand what the real issue is.
>Device drivers should live in the kernel. Period.
It would be great if it was technically possible to do this with GNOME, if this is your goal, I would encourage you attempt to merge all the hundreds of extensions together into one big tree, resolve all the conflicts, and then maintain that. It's probably going to be a lot of work, and will break a huge number of things, and if you don't want to do it... well now you understand why GNOME maintainers don't either. Until that happens, people have to stick to another approach: extension maintainers just have to use CI to check their extensions against master and keep it updated.
