I think this point is what the anti-framework does not get when discussing the topic. They fail to see how hard and unpleasant it is to handle all the real-world problems that hits any production environment with a "platform" approach, and at the same time they fail to see how javascript-based een frameworks not only solve them by making them implementation details but also go through great lengths to improve the developer experience.
Just take a look at JSX. It's where a great deal of the complexity of the framework lies, but simplifies everything so much. It's the exact opposite of platform features.
