I suspect this kind of thing could well be folded into Traveller…and some of it already is; as TL is defined as ‘what can be made locally’. Consider a TL-12 grav truck manufactured with TL-14 control systems imported from a TL-15 world. There could a lot of lucrative trade in shipping parts, not whole widgets.
