Then use Arch, or some other rolling release distro.

These are terrible solutions, not least due to the theming issue. Rolling release is the real solution.
Windows + chocolatey or macos + brew (cask) is better than any repository with dependencies on linux.
Also, do not want Arch or any <distro-name> - I just want LINUX (or Desktop Linux).
One predictable system, instead of many kinds/variants of basically the same programs - one system to hate, one system to deal with. (Arch wiki is good though)
What do you mean ? How can you have Linux without using a distro ? Are you saying there should be one official distro instead of many ?
And this is why I think snap/flatpack/etc model ("system" in system) is real solution for linux desktop.
Valve's Steam client already achieved same thing: provided one "sdk" for apps, one runtime (that developer can rely on) - because you can't have one main linux organisation like microsoft and apple.
Linux is kernel - I talk about good alternative for macOS/Windows, alternative desktop system, that can do much better than other two.
