I agree that apps/modules/libraries should have code separate from configuration. I see no problem with letting configuration be part of a _project_, however. Environment variables are too implicit in a lot of cases, and generally you end up having code checked into some other repository that makes sure the environment variables are set properly. I prefer to skip the middle man and have clearly demarcated sections of configuration directly in my projects.
