I don't think it is a good idea either. Let's not make things more complicated then necessary.
So in the now defunct Traveller game I was in recently, my Broker had a term where he got both Comms skills and a science. I figured, he may have helped out with either traffic control at the spaceport or coordinating cargo handlers. And also learned a bit about Economics while he was at it.
So he can operate a radio. Big deal. Doesn't mean he knows how to fix it. Or, in the case of Vargr or Vilani, how that damn thing even works. Vilani, because of their strange way of teaching tech skills and Vargr because, hey, if it works, who needs to know how? Yeah, these guys are curious, but mostly about things they can eat or otherwise exploit. So there.
