Just so.
RE the long timescale, I think the OTU designers picked a perfect span. It's far enough ahead to justify almost any changes in Solomani/Terro-human cultures the Referee desires but near enough to our time that the Referee can also retain all sorts of connections and familiar elements.
I also really like the Vilani. A Human race whose culture has focused on long-term stability rather than disruptive progress having been the dominant interstellar power for a long time, and still an important influence in the current era, makes a lot of sense for a strange but still comprehensible far future.
