I don't agree. If we know or have good reason to believe that the data is
completely bogus, then there's no point in retaining it. And having
different data for two zones produces a subconcious belief that both are
higher quality than if we just have the same. So where the data is
completely wrong, I vote for these merges.

I completely agree with this part.
