[Talk-us] Admin boundary level quirk in NYC

  So I propose a different schema:

  New York Boroughs: 9
  Cities (incl. NYC): 8
  Counties: 6

  and have separate relations for the counties and boroughs (e.g. Brooklyn
  and Kings County), sharing the same ways.

Your proposal sounds entirely reasonable to me.  The notion that cities
are contained within a county is baked into the hierarchical
organization, and something has to give when that isn't true.  Letting
the hierarchy not line up seems better than choosing different levels.

In the old way, there's the awkward question about how L5 should be
rendered, and why it should look different than L8, and that's all
unnnecessary mess.

Your proposal defers the interesting choice to the renderer, which is
whether one cares about counties or boroughs, but such deferring is in
my view a feature.
