[Tagging] Tagging natural or historic regions

Fuzzy boundaries do have their place. Currently we use sharp boundaries for
landuse, but often the boundary is really fuzzy. A wooded area would be a
good example of a where a fuzzy boundary might be employed. But the
fuzziness of a wooded area may only be a few meters. The fuzziness
of "Shakespeare Country" is completely different.

I agree that there are advantages to including fuzzy boundaries, but we
should first document how to tag these features.
