How about class E?
Let's do it. IFR stuck with procedural separation on the ATC freq whilst self-segregating with VFR on the CTAF. What planet are you calling from, MJBOW2?
Why on earth would anybody want E over an airfield if there wasn't enough traffic to justify D?
You NAStronauts have nothing credible to base your arguments on except "that's the way they do it in the US".
At least the boys at CASA have seen through you lot and are inventing their own airspace structure to keep the "show on the road".
