Looks like args and extraArgs was deprecates here:

https://github.com/NixOS/nixpkgs/pull/148315

imports = value._module.args.modules; seems promising, but as I add colmena.nixosModules.deploymentOptions to the nixosSystem modules, I now get a duplicate definition warning:

error: The option `deployment.allowLocalDeployment' in `<unknown-file>' is already declared in `/nix/store/4ba8vi60ay3b68kgspyxd7bmxbsixar1-source/flake.nix'.

and for reference, this is how i use it.

let
      hosts = import ./hosts hardware self.nixosModule;
      deploy = sconfig.lib.deploy { inherit self hosts; };
in
{
      inherit (deploy) colmena;
      nixosConfigurations = builtins.mapAttrs (_: nixpkgs.lib.nixosSystem) hosts;
}

./hosts looks like

hardware: nixosModule:
with hardware;

let
  sys = system: mods: {
    inherit system;
    modules = [ nixosModule ] ++ mods;
  };

in
{
   host1 = sys "x86_64-linux" [ ./host1 ];
}

./hosts/default.nix looks like

hardware: nixosModule:
with hardware;

let
  sys = system: mods: {
    inherit system;
    modules = [ nixosModule ] ++ mods;
  };

in
{
   host1 = sys "x86_64-linux" [ ./host1 ];
}
