Clarify purpose of InjectionPointConfigurator.bean(Bean<?> bean) method

Dear EG,
I would like to ask for clarification of javax.enterprise.inject.spi.builder.InjectionPointConfigurator#bean method. I am not really sure what's the benefit of this method and what would be the suitable use case for this method.

I think using this method when I have my custom bean doesn't have any significant advantage since I can declare set of injection points in my custom bean impl.

Maybe I would remove this method from the InjectionPointConfigurator interface.
