The only issue with the bridge staff is that audience's expected a larger showing of main cast to have stations on the bridge.
Trek as a whole has had bridge (and in DS9 case bridge and Ops) that have positions that aren't manned by primary cast. With those being played by either extras some of which are short term some of which are long term background with generally no lines", to minor bit players who generally might get basic lines like, "aye sir, course set". To more featured guest actor, with a significantly larger role, like Riley in TOS.
In fact character wise, the bridge crew of Discovery outside the primary cast, are actually very similar in usage to the characters of Sulu, Chekov and Uhura. And outside of the reoccurring Ro Lauren for the 8 episodes she is on the bridge, better realized characters then what TOS, TNG, DS9, and ENT featured for Bridge crew that weren't in the primary cast. And doing so with them generally with 60 episodes or less of screen time. I don't yet include SNW in the comparison at only 20 episodes, but to date DSC bridge crew outside primary cast is more developed.
And in reality the two shows that absolutely have no legitimate reason (in universe) to not have better developed or even the same extra portraying roles are Voyager which has no real means of changing crew and has a rather small compliment of crew. To Enterprise the smallest crew, though its structure does allow the possibility of new crew arriving through the seasons.
Ray Hardgrit, you do make a valid point that we should see other crew persons on the ship (and I mean all of them). Trek has done an utterly piss poor job in showing that multiple shifts for each station would be had every single day. Data's Day on TNG is the only one that I can think of the top of my head that recognizes this in the episode. Instead it's every mission that we see just happens to occur on one set shift when the primary stars are the ones on duty. Very much a weakness in all of Trek.
