I think the bridge crew comes down to the modern belief that the ST universe doesn't allow enough interpersonal conflict (i.e. people siding with Ellison that people in the future are just like they are now rather than going for a humanity that's learned some things and can dusagree but come together for the common good).
But much like Vulcans post TAS, the idea of professional crews that worked together slowly got eroded in TNG, DS9, VOY and ENT. Then blown up in DIS, PIC and LD.
(If you want a professional crew, Lower Decks ain't it, unless you can get into the send up).
