> deep / fast / craft-and-decomposition-loving vs black box / outcome-only

As a (self-reported) craft-and-decomposition lover, I wouldn't call the process "fast".

Certainly it's much faster than if I were trying to take the same approach without the same skills; and certainly I could slow it down with over-engineering. (And "deep" absolutely fits.) But the people I've known that I'd characterize as strongly "outcome-only", were certainly capable of sustaining some pretty high delta-LoC per day.
