This actually came up when we were talking about the shields last week. The
shields rendering is actually a full mapnik stylesheet, not just an
overlay. Phil pointed out that this is the only way to avoid conflicts. So
it is essentially a full osm.org mapnik stylesheet (from a few months ago
but it hasn't changed much recently) with the shields logic added in. It
could definitely be tweaked with more US-specific rules. Of course
osm.orgis about to move to a carto based stylesheet instead of the
hand-tweaked
XML that things are based on now. This is being done because the
hand-crafted XML is a pain to maintain. Not sure if we can port the shields
logic to that setup yet. But either way, yes there are definitely some
possibilities here.
