React is the view layer only so it's not all-or-nothing. That means it can be implemented in a traditional PHP website that's been sitting around for 10 years. And it's not overkill at all, it brings sanity to code and makes it more maintainable. You'll be able to do more with less. React is perfect for replacing turning your cooked spaghetti into dry pasta. Entropy for the win!
