No, I don't think so. It's possible to write a whole load of very clever things in vanilla JS, but it's not always a good use of time to do so, and it is not a very easy way to develop things in large teams, without building up an abstraction layer with getters and setters that is not appreciably better than a minimal reactive framework. The one-way data flow in reactive frameworks is the bit worth fighting for (and fighting over).
