Support for Nix packages (nixpkgs) and Guix packages
Both Nix packages (repo), and Guix packages (repo) can be used cross-distributions akin to Flatpaks and Snaps. According to https://repology.org, Nix has 68000+ packages, while Guix has 17000+ packages. Thus, if possible, integrating Nix and Guix packages to Gnome Software would be great.
