Also, official images are not production ready, they are apparently intended for development purposes. Take the Django image as an example. The server it runs on start is not Gunicorn, or uWSGI, or Apache. It is the development server of Django. I can do better than that myself.
I don't think that is a problem with Docker - the application. If Docker - the company - does not have the resources to properly maintain so many official images then it shouldn't try to.
