> Way simpler to do on Linux than M$ Windows.

Completely unnecessary on Windows since it is an operating system, not a kludge of random source code from the internet.

> I mean, flatpak, appimage, docker, etc ...

Which of those is ubiquitous enough to ensure availability of what you're looking for in that format? In my experience: none of them. AppImage is easily the best, but the community seems to hate it because it makes things too flexible and simple or something.
