We're actually aiming to build UIs that would match this level of complexity (if not even more complex), so it will be interesting to see how this pans out. I'm not massively concerned about it being an issue tbh (though thanks for flagging it) - the real issue that I'm concerned might swallow a lot of our time will be how we implement animations using this architecture (though we're currently looking to React JS for inspiration there).
That's what i was about to say : i'd be curious to see how this approach works when bringing animation into the mix, as well as complex uikit components ( such as tableview and collection views) which have their own optimized refresh cycles.
