Importing namespaced nixosModules

[TakodaS]

Suppose I really like the palworld server configuration you use in your config and i want to use it in my dotfiles. I setup my snowfall flake as follows:

#flake.nix
{
  inputs = {
    nixpkgs.url = "github:nixos/nixpkgs/nixos-unstable";

    snowfall-lib = {
      url = "github:snowfallorg/lib";
      inputs.nixpkgs.follows = "nixpkgs";
    };

    jh-config = {
      url = "github:jakehamilton/config";
      inputs.nixpkgs.follows = "nixpkgs";
      inputs.aux-website.url = "nixpkgs"; # I override the flake urls here because nix flake show errors out
      inputs.discord-nord-theme.url = "nixpkgs";
    };
  };

  outputs = inputs:
    inputs.snowfall-lib.mkFlake {
      inherit inputs;
      src = ./.;
      systems.modules.nixos = with inputs; [
        jh-config.nixosModules."services/palworld"
      ];
    };
}

#systems/x86_64-linux/test-system/default.nix
{
  config,
  namespace, # The namespace used for your flake, defaulting to "internal" if not set.
  ...
}: {
  config.services.palworld.enable = true;
}

This fails with the error
error: The option plusultra.services.steam does not exist.
because this dependent option is not loaded. To fix this, I could add ` jh-config.nixosModules."services/steam" to my module imports but this might depend on other internally defined options and would mean I'd have to manually keep adding modules until the dependencies are satisfied. On the other hand, i can see how polluting the global namespace might have nasty consequences down the line. Is there a smarter way I'm missing? Many thanks!

I think this is an issue with how that specific module is written rather than with snowfall itself. This line makes explicit reference to config.plusultra.services.steam so if you use this module, you need to have config.plusultra.services.steam as an option in your config, since it's not declared by that file.
