Well, the Scripting API contains an enumerated type for races, which includes several races not yet seen in the game, among them are Tholians and Andromedans. OP, of course, already has working Tractor/Repulsor beams. It's highly likely then, that it was Taldren's intention to include these races (and others) in later versions of SFC, just as the Mirak were added to SFC2 from SFC1.
