strange behavior of the config argument in submodule modules when using apply

default.nix

(import <nixpkgs/lib>).evalModules {
  modules = [
    (
      { lib, ... }:
      {
        options = {
          someOption = lib.mkOption {
            default = {
              foo = { };
            };

            apply = xs: builtins.mapAttrs (name: x: x // { inherit name; }) xs;

            type = lib.types.attrsOf (
              lib.types.submodule (
                { config, ... }:
                {
                  options = {
                    name = lib.mkOption {
                      type = lib.types.str;
                      default = "defaultName";
                    };
                    nameClone = lib.mkOption {
                      type = lib.types.str;
                      default = config.name;
                    };
                  };
                }
              )
            );
          };
        };
      }
    )
  ];
}

start.sh

nix eval -f ./default.nix config

Actually, apply didn't run on the input module but on the output value, the result of evalModules… I should have guessed that. And to solve this, there's already a builtin name argument in submodules inside attrsOf
