To me, this is redundant given layer=1 in the provided example i.e.
the presence of the building with layer=1 *already* implies
covered=yes for the section of highway under the building.

Perhaps this is just a problem with the renderer. I assumed, though,
that surely this issue has already come up at some point (and
therefore there must be some tag I have missed)? Are there really no
ways already mapped (and rendered correctly) that pass through a
building? Undercover service=parking_aisle's, for example? No?
