I wholeheartedly agree with everything you say. I don't see it as contradicting in any way 
principles that I outlined. It's just that sometimes doing a single logical change to the code 
requires a large patch and breaking it artificially into smaller patches might actually make 
matters worse. I believe this would be the case for this scenario. And honestly speaking I don't 
think that the patch here will be very big. But like you say, there's a compromise to be struck.
