The way to go about this is to see if breaking existing practice will break current implementations and plausible future implementations.
If that's not the case, though, consider that a correct implementation of DNS would be within its rights to take note of the "same serial number but incoherent answers" condition and declare the zone unreachable. I'm not
Would be pretty silly, and overstepping the robustness principle.
DNS is about fact, not value -- it's about mechanism, not policy. No matter how you slice it, intentionally incoherent DNS zones are "broken."
So by your logic, by making sure that the serial numbers never match, we would 'unbreak' the situation? Seems like a step in the wrong direction.
