There are now quite a few different Trek series nominated. I've approved AOS, and shopfront's AOS/DS9 crossover, which I think is quite a specific thing that wouldn't necessarily fit very well under "Kelvin timeline". As with some of the noms on the clarifications post, I'll give it 48 hours for the others, to see if there's any further discussion on this.

ETA: though it might be worth telling you that I've just seen "Star Trek" as a fandom on the approvals screen; this strikes me as very broad but I'm willing to be convinced by whoever nominated it. However, at present it only has the two default character tags and no worldbuilding tags attached ...
