Well said.  I don't have the energy to continue to engage, but I was
thinking this too.

Don't just build it, but build it, take OSM and remove landuse tags and
then-empty objects, generate the landuse polygons you think can be
created "automatically", and difference them, and then for those that
don't map, post a dataset and people can look at the differences.

Agreed.
