> I agree but does Flatpak actually work for CLI tools (which is where I see most use of curl-bash). E.g. could I install Rust using Flatpak? My understanding was it's more suited for sandboxed GUI apps.

Distrobox is basically flatpak for CLI apps. Not exactly, but it accomplishes a similar goal.

Doesn't it use Docker? Fine for trying stuff out on different distros but there's no way I want Docker as a normal installation process.

Docker is what you use if you've failed to do it the right way.
