75% of one, 25% of the other. I would not want to straightjacket Discovery by forcing the aesthetics of the 1960s on it, either in visually or in narrative, but continuity cannot be dismissed out of hand. Some changes should be expected, and hopefully the new series has room to breathe. Let's not forget that the setting was chosen as a means of explaining ideas and concepts that appeared in the original series, and to that extent stories should lead towards it. The Federation is unified, but it feels far less integrated than it would in subsequent series.I think it is interesting that there are references to a Vulcan expeditionary force, presumably another scientific and military force that is in competition with Starfleet. Perhaps until that moment in which the defense of the Federation is paramount, they remain separate from one another, coordinating, but with their own agendas. At some level, I think the series wants to explore how people of different backgrounds work together.
