Indeed, many distros tackle the reproducibility issue. But for the better part (and because of history), it can only be an after-thought, some extra layers that tries to fix the existing system. The fundamental difference with Nix and Guix is that it's "reproducibility by design". A much more sustainable approach in my opinion.
