I find the opposite true. Components based routing is fine for small applications, but in a sizable application you will inevitable end up with several things that doesn't fit nicely into the simplistic router component model, and now you're shit out of luck and have to try to jimmy-rig in some escape hatch. It's a much more flexible model to have the router update your state in Redux or whatever, and then you take care of all the rendering and component hierarchies yourself.
