I would have no real problem with that, though I'm not entirely fond of the prospect of having more air-quakeing buffs around, if ya know what I mean. 
I dunno, I fly buffs most of the time... and as a below-average fighter pilot and an above average bomber gunner... most people that die to my guns are:
1. Unlucky... sometimes you just eat a few in the face early on.
2. Not flying a ride that is conducive to tackling a later war heavy bomber
3. Just not a very good pilot
4. Impatient or rushed for one reason or another
You really can't FORCE a fighter into a fight with you as a buffer (although I have seen 999000 air-quake his way across airfields several times).
Withholding a reward/recognition on a very valid parameter in the hopes that it will discourage the minority from using the machine in a manner not intended... well, that would wildly change the landscape of the game were that philosophy to be applied evenly.
But, I am by no means vehemently supporting this addition, I just think it would be "cool"... I am sure I have about 3% of the big picture of everything that HTC goes over when making gameplay decisions.
