Finally, we can both agree that jquery dom manipulation is a great way to find yourself in a mess of unmaintainable code.
If you're a fan of backbone views though - why not React? IMO it's very similar to backbone but with sane structure and an incredibly powerful render loop.
Now I think the idea is awesome and architecture that arises from it might be very good. But this idea assumes that DOM manipulation is fast enough to do every render frame and I do not trust yet the caching magic that React.js conjures to ameliorate the fact that it actually isn't.
