Ah yep, I eventually came to this conclusion myself.

Heh, because I don't know what it is! It's often hard to tell the difference
between a large rural property, a farm, or even some kind of light industry.
Maybe I can see buildings and sheds, but that's all I know. Your "area=yes"
suggestion is interesting.

Slightly related note, is it ok to use tags like "landuse=residential" at
vastly different levels of granularity. Ie, it could be a house, a block, or
what I've been doing at the moment, whole suburbs. I'm trying to sketch out
the western edges of the urban sprawl of Melbourne. At the very least, it
gives a guide as to which suburbs are remaining to be mapped - looking at
the map gives a false impression as to the level of completeness, because
unmapped shows the same as unoccupied.
