It's a great question. I think it drops the barrier for individuals who don't want to spend time learning other languages or concepts. What's a Dispatcher and why is it important for the UI? Some of these developers may never need to answer that question -- and that may not be a terrible thing.

Things that allow people to do more with their existing skill set, even if it's not the most efficient, are generally good. They support organic growth of platforms, creativity, and exploration of things that were previously out of reach for some individuals. They can certainly become unmaintainable and problematic, but if the app's usage grows to a point where those are important problems to solve, they will get solved. Or they won't and they'll become a limiting factor in the usefulness of the application.

Evolution is a fantastic thing ;)
