Deveroper/packager productivity matters a lot, as people will then bother to package more nice things and keep those packages up to date. It's bad for everyone if packaging is needlessly hard.

Also the sw engineering world is clearly moving away from packaging as "integate application into distro X version set of library versions by continuously expending a lot of integration engineering effort" and more towards things like docker images, snap/flatpak/appimage that sidestep the problem of host platform component dependencies as much as possible.
