I'm not sure I understand your question correctly, but you won't be forced to aim down the sight all the time when shooting. You'll be able to fire from your hip as well.
Speaking about aiming, any plan for dual wielding?Various augmentations will be able to improve firing from the hip so it will be viable to use both ways of shooting. Sight, however, can also provide some additional bonuses.
Edit: Fixed for inconsistencies.
I think OP's talking about GTA 5 style of aiming. In GTA 5, if you aim in first person, some guns will not let you aim down with iron sights, and the gun will just be off the side. It looks like hip firing, but it really isn't.
Something like this:
This type of aiming is basically simulating "high shoulder pocket", which from what I understand from friends and fam in the military, is a valid way of aiming. Obviously, not as accurate at aiming down sights, but it is preferable in some situations. (I guess. I have no idea what those situations might be. )
