It's important to realize that everything you are asking for was tried long, long ago and discarded. For example, the original Confirmed Kill (which turned into Warbirds, which turned into Aces High) had very high torque making takeoffs very difficult. There is no question whatsoever that the current AH torque on takeoff is weak. Comments by real pilots indicated full rudder was needed on Spits on takeoff, while AH requires only a tiny bit of rudder. But the difficult high torque takeoff in CK was removed because it was unpopular.
Engine management is the same thing: more than ten years ago Air Warrior had what you wanted. Run at full power too long and the engine overheated and quit. They even programmed rare random failures under normal engine operation. More realistic, indeed, but the player base emphatically hated it and it was removed.
Same thing can be said about icons.
In all these cases the programmers actually listened to their customers and modified their game to please the majority. It is always a balancing act and since online flight sims have had a very long time (about 15 years) to get it right, then what we have now is close to right for the majority.
