I don't think there's a need to change anything from your current
strategy, but we should be clear in the docs:
1. Finders should *not* assume their parent packages have been loaded
(and should not load them implicitly)
2. Loaders *can* assume their parent packages have already been loaded
and are present in sys.modules (and can complain if they're not there)
