I have been looking a little further at the issues surrounding limitingly thin metal layers. Setting a metal layer thickness to 0.0, (air/vacuum on each side) still gives a finite reflection. This holds whether the metal is patterned or continuous across the simulation volume. It also - apparently - holds very generally whenever any Drude or Lorentz type term is included in the material definition.
I'd be grateful for any input here - is this just the wrong approach to use for (finite) thin metals, or a bug? Is there a workaround?
