Sulu got a first name and a birth place a mere 20 years after he was introduced, what more do you want? Season 4 has writers for 13 episodes https://directories.wga.org/project/1134306/star-trek-discovery/
Right! I referred to that earlier in the thread, it’s a large part of the preponderance of evidence I was referring to in the post you quoted. What caused the initial confusion was the preview for episode 11, which was referred to as the season finale on StarTrek.com, which must’ve been in error. It seems fair less likely/totally implausible that the WGA, and several actors from the series are mistaken about the number of episodes.
