Rory, I agree with you - there are always corner cases. And while we concentrate on the geographical aspect (e.g. "somewhere there might be a large territory where the tags mean different thing"), the corner case can actually exist in our own neighborhood, simply because our neighbor understood some tags to mean something different.
To use the a handball vs team_handball example - if it wasn't for you, no one would have been aware of such a distinction, and if we had a @talk discussion of the global bot autorename to fix it, there is a good chance it __might__ have been overlooked, and damage would be done - we don't have as many people monitoring @talk, as we have actually mapping things. But if someone made a challenge to convert handball->team_handball, someone would have caught it in your area, thus flagging the issue globally, documenting the distinction, and cleaning up the other areas where having a mix of both values is incorrect.
