Rails::Paths.add optional module?

I use (and I know many others) uses the “/app” folder to add folder to extend rails. Some examples would be FormBuilder subclasses, Decorators, etc.

My problem is that app/{my_extension} pollutes the global namespace. I would like to have app/form_builders use the FormBuilders namespace so I can reuse class (My model class). I understand that it may be hard to implicitly add this feature as it would directly conflict with how app/controllers and app/models works.

However, adding an option to paths.add “app/form_builders”, :module => FormBuilders would allow someone to namespace their project.

Good idea?
