Thinking about it, duplicate a or aaaa records are also valid. There should also be a setting for how the round-robin/cyclic load balancing works in this way.
So maybe bin the duplicate record detection section entirely, then add a new drop down for load balance policy (or set to a standard cyclic for all dns zones)
