Hi -

I don't have a direct answer I'm afraid. But please try not to think
about "what gets rendered" - the default style shown on the osm.org
homepage is just one of hundreds of rendering styles that are used. If
there are existing tags in use, great, whether or not they show on the
osm.org rendering. If not, then maybe you and others can think of
tagging that represents things properly - get the semantics right,
leave the rendering to the renderers.
