What if I wont to be able to do something like this in flakeB:

{
  inputs.flakeA.url = "/path/to/flakeA";
 outputs = inputs: inputs.flakeA ./. {};
}

What if I want to be able to do something like this in flakeB:

{
  inputs.flakeA.url = "/path/to/flakeA";
  outputs = inputs: inputs.flakeA ./. { inherit inputs; };
}

in flakeA, I did something like this:

{
  inputs = {...};
  outputs = inputs:
    flakelight ./. {
      imports = [
        flakelight.flakelightModules.flakelightModule
        ./myfeature.nix
      ];
      flakelightModule = {lib, ...}: {
        imports = [./myfeature.nix];
        inputs.flakelight = lib.mkDefault flakelight;
        inputs.home-manager = lib.mkDefault home-manager;
     };
   };
}
