Yeah but a shot down is a shot down, regardless if it's from air to air or surface to air. How often are we going to see a real air to air combat today either from within or beyond visual range anywhere in the world?
By the looks of how things are shaping up in the past two decades. It is all but certain (God forbid) that we may actually be alive when that happens. Exchanges between the US-NATO and Russia-China in the Black Sea, Barent Sea, Baltic states, South China Sea, Syria and so on. It is inevitable that an air to air confrontation be it a skirmish or full scale war, would happen!
