There is some validity to the request.
You don't need a hanger to unjam a weapon, you don't need a hanger to gas it up. You don't need a hanger to top up the oil, or anything like that.
If fuel has been hit, you should be restricted to whatever the limit is. If ordnance is hit, no ord. But I would be absolutely amazed if all of the fuel was kept in only a few places, same with ammo.
