It's a two-step thing. Of course you should be able to map the building
and say "this is an area". But the renderer might *still* choose not to
render it as an area (think e.g. of certain kinds of airspace which are
areas but you will usually only render the outline).

PS: Not that we want to map airspace. I just found it a fitting example
given where you're hailing from.
