Yes I know it's not for all parts of your application, but often in admin interfaces you need something quick and dirty that does CRUD - the scaffold controller is a good starting point for that. Yes you have to go back and delete some code, but it's way faster than building it all from scratch.
And you would want it to respond to json if you were using something like angular on the front end to do two way databinding. Yves - that's exactly the feature I'm looking for.
