Well, the way I see it - these tools open up whole new array of possibilities of writing code in a more intuitive fashion. This may enable a completely different and cleaner architecture or a mess. Probably as always it starts with a mess and results in clean along the way once you resolve all the problems you should know about but didn't. Key point is that this is exactly the way our languages and industry evolves. jQuery also started as someones just-for-fun project and poised risk (and still does) to all the projects that used it. In reality a person needs to go and just use stuff like this, with experience you learn to see if something works or not.
