Looks like MVC/MVVC, something that has been available to do in JS since long time ago (Backbone.js was a popular option for doing a modified version of this). Or I'm missing something obvious. Care to explain a bit more in detail?
The point here is that you can write maintainable, clean, efficient JavaScript web apps without the load of complexity added by React.
No, Backbone.js doesn't do 2-way data binding, although some certainly made it do that. But it doesn't by default, it has a 1-way data binding (the UI updates when the model changes, but doesn't update the model automatically when the UI changes).

What? Who does that? I certainly didn't and I haven't heard anyone in my +decade of web development.
