Well, in the Bakersfield example, thanks to the residential outlines and
trees, I spotted a median and an alley way that hadn't been mapped
without having to open an editor and WMS first.

True, but you can have military activity in a street.  Heck, a military
could take "Occupy Wall Street" literally.

No, but that would be analogous to a private/permissive living street in
an apartment complex.  Same owner, area and ways used for other uses.
Granted, there's a bit of a judgement call in play, but I'm pretty sure
anybody who is intent on using landuse=* knows how nitpicky zoning is;
ideally landuse=* and zoning should be as congruent as practical in
regards to property lines and actual land use goes.
