I mean, imagine DS9 if every single episode was from the perspective of Sisko. No other characters ever got "focus episodes." In fact, we never even saw scenes between supporting characters unless they were absolutely needed to move the plot forward. It would get pretty tiresome having Bajorans tell The Emissary how awesome he was all the time, and seeing Sisko single-handedly resolve every crisis of the week.
I guess a fairer comparison would be to a show like Highlander, MacGuyver, or Xena? Heroic lead, with everyone else clearly playing supporting roles. However, I don't recall the same amount of character shilling in series - where everyone either talked up how amazing the main character was, was jealous of the main character, or was secretly in love with them. The mains got to save the day almost every week, but the wider character world was often indifferent or hostile to them.
Keep in mind, I'm just talking about Season 1 of Discovery here. Season 2 had its issues, but it handled Michael much, much better. More show, less tell.
