It's probably slightly useful.  But zoning is prescriptive, and for the
future.  Often there can be non-residential uses in areas zoned
residential, and they're called "pre-existing nonconforming use".  And,
some areas zoned industrial can just be trees.  Near me, one such area
is being converted to housing -- there is a law allowing builders to
ignore local zoning if a high enough fraction fo the new units are
affordable.

So I would only want to use it as an overlay to help guide the process
of where to draw landuse polygons, but with local knowledge and thought.

CC-BY-SA is incompatible.  That's why the great license change was so
painful.
