Support for system-manager

I got this flake.nix:

{
  inputs = {
    nixpkgs.url = "github:NixOS/nixpkgs/nixos-unstable";
    nix-software-center.url = "github:snowfallorg/nix-software-center";
    system-manager = {
      url = "github:numtide/system-manager";
      inputs.nixpkgs.follows = "nixpkgs";
    };
  };

  outputs = { self, flake-utils, nixpkgs, system-manager, }: {
    systemConfigs.default = system-manager.lib.makeSystemConfig {
      modules = [
        ./modules
      ];
    };
  };
}

And this in the default.nix, the config for for system-manager:

    environment = {
      systemPackages = with pkgs; [
        inputs.nix-software-center.packages.${system}.nix-software-center
      ];
    };

This is the output:

Is this up to system-manager, or your project?
