There are so many development frameworks now - and I'm sure this one is a great addition to the list. That said: I wish the framework developers would work together to create something awesome for core, which is where much of this really needs to be.

Core needs standard markup for option data types, to be output via do_settings_sections(), standard sanitization/validation callbacks for option data types, and the same for custom post meta boxes and meta data. I think the best people to make that happen are the developers who have put so much time and effort into defining all of those things for their frameworks.

Maybe we can lock Benjamin, Devin Price, et al in a room, and tell them they can't come out until they have a patch? :)
