Wouldn't it be easier to solve this by offering a Flatpak or a Snap? I mean... The alternative is to have a package for essentially every dist.

It might be easier if you don't have package maintainers that take care of the packaging work and integrate everything nicely into each distribution. But there are good reasons to provide packages for distributions as well.

BTW some work has been done already regarding Flatpak and Snap.

There should now be an artful distribution available via our standard .deb install instructions.
