>you can have one team working on the API and one on the interface and the only place they really need to communicate is in the API documentation

That's already how you should be working anyways. Unfortunately, most language don't seem to have support for a decent template system that makes this natural. People need to start making heist clones in their language of choice so doing things right becomes more common.

I agree, but it's often too easy to just add another variable in your controller then modify the view, and now there's undocumented functionality. IMO the full separation is more helpful to stay DRY.
