You're totally right. If you're a package maintainer and you find out some package is misbehaving even though all if its included tests pass, it might kinda make you feel like kicking the thing and calling it junk.

But we should recognize that some of what drives that is just defensiveness, and some is personal frustration. At the end of the day, Nix and Nixpkgs are for letting people run useful software more or less as it exists. It's not just for users or developers of perfectly tested, bug-free software. (Nix itself is certainly neither of those things, and neither is Nixpkgs!)
