Other assignments I've worked on could just have the settings files as part of the project. Only taking out the secret keys etc. -- However, this is meant to be generally useful for third-parties, and I don't think we all should have our configs in this project.
Also, it's eaiser when it's just one django app, and you don't expect to give any project at all. But this is in-between those. It's no single pluggable app, it's meant to be used as a project, but django does not always make that super easy.
It's worth looking into what other projects do here.
