Where contributors are the audience, yes. For things like libraries, I care about those things only if I run into a bug, and have enough resources to attempt a fix.
It can help even when using the library and not contributing. It helps you to use the api better imo, because usually the abstraction is not perfect and having even a general sense of how the sausage is made will prevent you from falling victim to gotchas. But then on the downside it lowers the mystique of the library. Some coders prefer to be magicians.
