Well it would if they were then trying to run code compiled for that
OS on the simulator.

Hmm, well that could be done.  Personally I would hold off doing it
until there is actually a situation where it is needed.  At the moment
support all three SWI interfaces simultaneously is not a problem.  So
unless someone comes up with a real situation where it causes problems
I would leave things as they are.  (Just my 2 cents worth).
