Well, maybe so. However, the game as it stands does not require entering a hanger to unload and the unloading is instant. So it already breaks any sense of realism in this case. I'm all for following lore but I think it becomes a rather thin argument that some aspects of an operation be rigidly maintained because of lore while other aspects of the same operation are ignored presumably for game play reasons.
its merely for convinience,
You want realism? in reality, trading is not as easy as buy then sell.
Alot of like custom, taxes, permit, documentation. And yet they are not in the game even if you buy from one superpower system and sell it to another.
As a person working in logistic sector, the game already broke the realism when i can buy and sell without any preparation
Common sense dictate that unloading out in the open is also a safety hazard.
Imagine that drifted cargo cause a major accident.
