That's about what the author says right at the top of the article. However, this is only more flexible in the front end. If you want to do anything with your data in the back end, a JSONField will help you less than fully structured data. While you can do some queries on JSON fields, most of the richer queries will have to be done in python, slowing processing down. If you're looking for runtime-changeable, structured data that you can run complex queries on, ModelModels sound like a good alternative. Most enterprise applications are in this area.
