But it /is/ broke. technically we never needed zones and the implementation was broken from the beginning. Bath and seen4by are 2D only and that is broke. We worked around that shortcoming, but that does not change the fact that the implementation of zones was broken from the start.
Having said that... now that zones are here, doing away with them would probably be an operation that the patient would not survive.
So instead of "don't fix if it ain't broke", I would say "watch out for a cure that is worse than the disease".
