I'm curious, why is this the case? Those seem like unneeded pieces of HW. What if there were many small, computer controlled air & fuel injection ports to provide very precisely timed ignitions as the rotor rotates through the compression zone? So instead of 1 or 2 ignitions (my 12A had leading & training spark plugs), there would be an entire series of small power inputs to the rotor. I'm not sure how the exhaust gases would affect the next ignition in the chain - that might be a big problem.
The US knows absolutely nothing about Aussie vehicles. Falcon? Holden? You have an entirely different universe down there!
Where I come from, a Ford Falcon looks like this:
