Random thought:
What would people think of having a separate "Hardcore Arena," with more sim features including things such as:
1. Complex engine management - Manual supercharger gearing, fuel mixture, etc.
2. Disabled ammo counters.
3. Friendly Dot Dar only within radar range.
4. Halved icon distance.
5. Full day/night cycle.
6. Complex bombsight.
7. Additional components for damage modeling - Control cables, oil and fuel lines, degrading control surface/wing effectiveness (damaged wing skin looses lift, damaged ailerons are less effective, etc.).
8. Damaged structural components might fail under excessive stress (IE, a damaged wing might rip off more readily under G forces than if it were intact).
9. Modeled pilot responsiveness - Aircraft modeled so controls account for historical machines not having HOTAS (IE, some aircraft might not be able to manipulate flaps and throttle simultaneously, delays between activating control on stick/keyboard and actual effect in game to reflect this, etc).
That way, those players who would like these more advanced features can enjoy them, without affecting the main server population.
