As I've said in the past, I think the scenario with people wanting "more" of the bridge crew dates back to a disconnect between the scriptwriters and the visuals team and the direction in Season 1.
Basically, it was very, very clear given the way the show was scripted the bridge crew were meant to be unimportant - just there to spout off a couple lines of exposition, nothing less, and nothing more. But the designers had fun with a few of them, giving Detmer the prosthetic and undercut, Owo a nice distinctive haircut, and Airiam very detailed makeup. This was really different from how Berman Trek treated the extras - where they were meant to look as boring as possible, so as even when they got a line or two, we never noticed they were in 50+ episodes. In addition, the camera treated them like characters, often lingering on their faces for "reaction shots" after a main cast member said something. These cues made people read them not as props, but people, and left people wanting to know more about them. And frankly, they started catering to this fan desire as early as Season 2, giving Owo a backstory and Airiam an entire episode, and continued in Season 3 with Detmer getting an entire PTSD arc.
I don't think we necessarily need to know more about the bridge crew. But I think the writers to some extent continue to struggle because the main cast doesn't align with the bridge crew, which means that traditional Trek stories can't be told without finding some way to shoehorn everyone in each week. I also do think it would be a nice change of pace to have a "Lower Decks" style episode where we followed the bridge crew and got to see the mains from their frame of reference instead, but that's a like to, not a need to.
