The staff seems to have been hard at work smoothing over the oddities from the "Wild West" days of pre-2010 Discovery, so a lot of the things from the past wouldn't fly in today's server environment. One major example is that most factions with questionable or import origins were removed or altered to reflect a more unified Discovery canon, and new import factions are fairly well policed by the community. Another is the current push for the removal or integration of guard systems.
As a community we've become more focused on the continuity of the universe than we were before and I think that's a good thing overall. Non-Nomad aliens is just the next debate in what is or is not a part of official Discovery server and/or mod canon.
