I think a large problem is in our psychology of not wanting to scrap our previous labor even if it was substandard. At this point I hope most coders are checking in code regularly enough that they could identify a point close to where quality declined and could throw everything after it out. Personally, I usually start a day with a review of the previous changes but I rarely back out low quality changes. I often realize a continuation/rework has taken longer than a full backout and redo (and I have virtually never been disappointed by a redo,) yet there is a psychological barrier to overcome before backing out.
