Much more work load have planes with variable prop pitch like early 109s and early russian planes.

Right, and there is not only prop pitch. Engine cooling is also "undermodeled" in IL2. Try to dive with cooling flaps open without power from 10000m. The engine will still run perfectly once you are at sea level. In RL you had to close these flaps to prevent the engine from getting too cold. Some other planes could be overboosted like the P47.
It might be interesting to watch player killing their machines because of abusiv operations.
