As a dev, you can just distribute a nixpkg with whatever build tool inside. That beats the current system of “native” packages where your software is repacked and then maintained by half a dozen teams for different distros that use different dependencies and update cadences.
Bottles has gone as far as to demand its fedora package be removed and now shows a warning if you’re not using the flatpak version because repackers just don’t properly test all their software (how can they? there are thousands of apps in these repos!)
