Err, guess I'm not popular opinion here, but I'd rather see the destroyed runways (and general non-paved terrain) have some bump and bounce to it, enough that you'd only attempt to land there in an emergency.
As for strafing it, I think several thousand rounds of 20mm would mess a runway up a bit (but I'd agree it goes too easily.)
