How does it stack up against traditional package management and others like AUR and Nix?

I think their uses extend beyond obsolete software. In particular, trying to get updates out to a wide variety of Linux distros has generally meant a tradeoff between “move fast, break things” and “move slow, never change”. Flatpak gives you a stable set of libraries to work with and the ability to run multiple versions of those libraries at once. Linux package managers have a place, but their sheer proliferation means that for most applications to reach all desktop Linux users, they have to go through something like Flatpak for distribution.
