Perhaps I should not have aimed for brevity.  I would not expect a router
or any other data consumer to infer access tags from a parallel way.  In my
theoretical sidewalk where walking is not allowed I would expect the
separately mapped sidewalk way to also be tagged with foot=no.  In case
it's not clear, I mean this as a joke and I don't expect this would
actually be sensible tagging anywhere, but who knows.  Essentially I'm just
saying I don't think putting foot=no on the main roadway when sidewalks are
mapped separately is helpful.  Just tag sidewalk=separate.
