I doubt it would happen, you already have a kill rotation button, it is called Flight assist ON. It really isn't difficult to learn how to stabilize a ship with FA-OFF, it is the most basic part of learning to fly FA-OFF.
With all that being said, I am never against additional functions that are optional. Just can't see the devs spending time on what is essentially training wheels for those that would like to use FA-OFF
As I said, I understand the established contempt for people who want features perceived as "making things easier". "Training wheels", in fact, for someone who's played this game since beta, for someone who spent years playing EVE Online, for someone who's flown thousands of hours on flight simulations, who was more than capable of flight and combat in First Encounters with full Newtonian dynamics (and is only sorry that flight mechanic didn't make it into ED), and in whose military-sim days used to enjoy lofting freefall bombs onto targets by eye in Falcon 4 just to see how accurate I could get (fairly accurate, for the record).
But what I was trying to explain was that the things some gamers will see as Filthy Casuals wanting an easy mode can sometimes be simulation enthusiasts wanting simple features in a 34th-century setting that are pretty basic here in the 21st (and which are jarring in their absence). For some people it's not about "can't". I'm quite capable of zeroing the rotation of my ship manually. But it's a pain in the a... donkey. It's not that I can't - it's that I don't want to have to bother, and honestly I can't see why anyone would.
