It's waste of resources. Fedora does mass rebuild once per 3 months at average. If libc gets a security fix, dnf in Fedora will download just a delta between packages. Lower consumption of resources mean faster turn-over rate and is better overall. But I can mimic NixOS behavior with mock (tool for clean rebuilds) and chroots or containers, if I want.
