Having gone through the thought experiment of applying that rule to the 
data I help maintain, I disagree. For one thing, it's quite backwards 
about the burden of proof. Essentially the rule you're suggesting is 
"Here's a Zone; it should go in unless someone can prove me wrong." And 
even if that were fixed, I see waaayy more opportunities for debate and 
disagreement if the standards for including data become more subjective.

I'm not saying we can't change the guidelines. But it'd need to be done 
carefully (and after the next release; I'm a bit rushed now), and any 
revision to be practical would have to be a lot more selective than what 
you're suggesting.
