occlusion is a lot cheaper then detection so that should be doable Dev time permitting of course

I certainly support having target occlusion for NPCs, we need that for a lot of future development. But I should be clear that even with that, there may be circumstances where people get hit and they think they shouldn't. Ie, where some part of their ship may actually be sticking out and visible to the NPC, but they aren't aware of it, and the NPC still hits them with a shot targeted for center-of-mass (the concealed part). So, occlusion would solve probably 95% of cases, but not all of them.

That would be okay with me.

I thought NPCs already had target occlusion. The conquerable station turrets stop firing at you if you hide behind an asteroid.

Not the levi turrets or the Deneb turrets.
