I posted something related to this earlier when I thought it was just a Yor thing, but if I'm scanning the XML files correctly for the Beta released on 12/14, the only cultures that can do anything to improve overall efficiency (adopt an advanced governance technology) are the Drath, the Korx, the Krynn, the Torians, the Terrans, and, most fascinatingly, the Korath.
I can read this situation at least two ways. First, cultures like the Iconians and the Yor are "anarchists." They have no government to improve. Second, this is still a beta thing and we have yet to see new items added in the unique trees after Alliances for some cultures like the Iconians.
I'm hoping the second reading is closer to being accurate. I can see how the notion of a Star Federation makes no sense for Yor or Thalans. But shouldn't advanced Yor have improved command and control protocals and advanced Thalans' hive queens produce more effective pheromones?
