You might have a module that you don't import at all, but does define 
components you want to be wired up. How is this module going to be 
registered? You could import it after all in some module you *know* is 
going to be imported (which one?). It seems rather easy to make a 
mistake here and wonder why things don't get configured. Plus you're 
importing stuff that you then don't use.

You could do the wiring using class decorator side effects, but the 
module will still need to be touched to get the decorators to kick in.
