if I want a flake output of nixosConfigurations.hello-world but need it to exist for each system architecture, is there a trick to do that? Doing this:

let
    forEachSystem = nixpkgs.lib.genAttrs [ 
      "aarch64-darwin"
      "aarch64-linux"
      "x86_64-darwin"
      "x86_64-linux"
    ];
  in {    
nixosConfigurations = forEachSystem (system: {
   hello-world = nixpkgs.lib.nixosSystem {
        inherit system;
        modules = [
          # include our module
          self.outputs.nixosModules.default
          ./examples/hello-world-configuration.nix
        ];
      };
      default = self.nixosConfiguration.${system}.hello-world;
};

almost gets me there but it makes me do nix build .#nixosConfigurations.x86_64-linux.hello-world but I want to get rid of that x86_64-linux part of the command and cannot figure out the trick to do so.

ayoooo guys im having trouble setting wifi passwords in my nix flake so that my laptop will connect to my home wifi network by default
i have setup like this:

networking.wireless.enable = true;

networking.wireless.networks = {
  "Bonkek" = {
    psk = "Kek12";
  };
};

where my hotspot is ubiquity with wpa2/wpa3

Is anyone well-versed enough in Flakes internals to know how Nix turns a flakeref string (i.e. "github:nixos/nixpkgs") into a URL? Or, if it doesn't do that, how it works with the input without having an intermediary URL stage?

I have a project where I take the flake.lock data and reconstruct the input data into a URL, so I can use git ls-remote and see if the input has changed at all (so I can see which inputs would be updated, without waiting the 15-30 seconds for nix flake update to run). However, I've run into less easy input types to work with, and it's made me question whether I'm reinventing the wheel here.
