I'll give one example, previously waypoints were read at mission start. Now they are Dynamic and have to be transmitted over the network. This communication needs to be tested and verified as functioning correctly. This happens for most new features.
So for every function added most of them need corresponding net code and lots of testing.

There is no right or wrong, it is purely personal preference of the flyer. Unless you have a stick with the throw of the real Mustangs stick, it can't be defined as anything approaching "Realistic"

I believe it is because developing for the old engine is very difficult with the rather rudimentary tools available. Supposedly a proper SDK is being developed alongside EDGE, to vastly improve this situation.
