I would argue that the DOM is broken for current requirements and their approach is actually quite sensible - circumvent it. What I would have like to have seen is a proper, UX designer led update to hardware accelerated UIML language that is not 3D and is not HTML. This project takes a good step in that direction, in the same vein that Bootstrap and others have. Lots of programming and design hours are wasted because the DOM is intended for Documents and not user interfaces.
