Show of hands--who here remembers the part where V'Ger calls out Spock while he's on Vulcan?
You mean the same half Vulcan Spock who possesses telepathic abilities, practised Vulcan mental disciplines for years and has previously been shown to be affected by a ship crewed by Vulcans being destroyed as opposed to the completely human Michael Burnham with none of those abilities? Yeah, not the same thing.
But the belief that the reason DSC's format needs to change is because no other Trek show has featured (at the most) 1-2 main protagonists who were at the heart of all the important stories, is provable bunk.
Obviously the format can't change now because the whole concept is that it is Michael Burnham's story which undermines your second point as it isn't comparable to previous Trek series as this is the first Trek series specifically intended as being one particular character's story. It is simply my personal opinion that Discovery would be a better series had it retained the same character dynamic seen from TNG - ENT rather than focusing on one character.
