I am very surprised to not see this in the release version. Stardock, are you kidding me? I recall a Stardock poll that was up for awhile asking people what race they most looked forward to playing. The resounding majority answered that they wanted the "create your own faction" race. It is clear that the devs knew that this was something the community wanted. In the betas, when the early faction creator was removed, there was a slight uproar but the understanding, if I recall, was that it was going back in later with some tweaking. Now at release, the response is that it should get added back later (again!).
I could try fiddling around with xml files, but that really shouldn't be the expectation to "fix" this issue. Regardless, I'm sure that the faction creator will get added back at some point, but I am certainly disappointed that it isn't in already.
