I share your fears, but I think the premise itself is valid. The project should be done, but fully Open Source.

I'd love to have Android (well, GrapheneOS) style sand-boxing for every app, I'd love to have it's granular permissions for every service. I'd love to have the battery management, the unified settings UI, the effortless disk encryption UX, ect. Who's using power, who's using data, who accessed the microphone 10 minutes ago?

Could this all be re-implemented in a Linux distribution? Sure, SE Linux is there. But it would take a long time to get to the same level of UX, and almost certainly fracture across different desktop environments.
