Nope, you've got it. Code-consistency is a property just like any other property, e.g. correctness, efficiency, testability, modifiability, verifiability, platform-agnosticism. Does it beat any of the examples I happened to list? Not a chance. > worrying about breaking everyone else's code You already said it, but just to expand: if you already have feature A, you might succeed in plumbing feature B through feature A's guts. And so on with feature C and D. But now you can't change any of them in isolation. When you try to fix up the plumbing, you'll now break 4 features at once.
