Agreed! Do you have an example you could link to? It looks like a
ticket has already been filed for mapnik:

Is it? Can you explain why? Conceptually, all you need is layer=* and
the ability to detect the overlap of the building=yes area and the
highway=* way. But I guess you're saying this is hard to encode with
"render rules"?

If so, I guess this is now off-topic for the tagging list.
