MVC frameworks like Django, Rails, etc, are not headless by default, as they take care of all frontend rendering. Headless = frontend and backend are fully separated; the "promise" was to have the backend be used on multiple projects. You would have a headless backend, then a web frontend project, an iOS one, an Android one, etc without having to rewrite any backend code.
