In a sense this is about the fundamental difference between frameworks and libraries. So to a certain extent, you're right. But there's extra complexity in not knowing why some annotation was picked up. With any API call you know you're trying to register something and can debug into it. With an annotation project you're sometimes stuck at "nothing happens".

Which is also true for node projects I guess :D

And the metaprogramming comment stands IMO.
