Yup. 
 But Allah is in the details. 
 Useless stuff can sometimes, increase immersion to incredible levels. And in that case, it's not useless at all - it highly improves the way how we see the game. 

 Think about the;
* gun flashes reflected on the fuselage
* spent shell casings dumped
* gun smoke
* visible rudders/stick in cockpit
 and etc etc.. these are all 'useless stuff' which was introduced in AH2(well, the gunflash thing in AH1..) - which made the game cooloer!
 So bring on the 'useless-but-cool' small stuff to AH2!!
