Most dogfights are done by missiles these days. You lock on, fire, and forget. A ballistic projectile wouldn't be useful at those ranges. I guess if AI fighter jets change progression to bring things back to close-in combat something like that may be useful. I don't predict it'd happen, but there's a chance. Missiles can just pack so much more thrust-per-second into a small package than a jet can, but AI jets could be a lot more agile and essentially a missile firing missile, or similar, letting them close distance better whole avoiding incoming ordinance.
