If that is actually the case then I’d expect the use of missiles/ammo to consume multiples per shot at non-dogfighting ranges.They have never had a slow rate of fire, they just make an attack roll less often. I think we can assume an attack each round, just like in space dogfights.
It's just difficult to hit at longer range, you need a few shots to get a hit.
FF&S required a RoF of ten shots per space combat round to get a single normal attack.
I think space combat is best represented as being either similar to classic Star Trek (shots taken tens of thousands of kilometers apart) or like Star Wars with WWII-like dogfighting. It seems difficult to accommodate both styles.
