If thats what you want them to do, warm seats, you're the employer.
FD fighter jock system is fine as is.
Cake and eat it.
The current NPC crew system is a minuscule shadow of what the devs had planned. There were supposed to be multiple roles (including pilots and gunners and even robotic crew for certain tasks), and we were given litterally one npc type with one role to fill.
There's no telling wether they'll iterate further on the original concept (my guess is they want to and have to contend with limited resources), but this being just a game, after all, there's strictly no reason to defend not expanding the feature.
