For me, having them look like TNG Klingons doesn’t even solve the problem because ENT had implied that shouldn’t happen until the TOS movie era. They could have rendered explicit the implication that not every Klingon was infected by the virus, but that still doesn’t support making the Klingons look how they did in s1 DIS.
Folks forget the klingon’s made that Augment virus which then got loose in a lab breach. If they could do that to themselves on accident imagine what they’d do to themselves on purpose to try and compensate as the implications of the augment virus turn thier society upside down. There’s much I don’t like about Disco Klingons but the face redesign intrigued me as a potential reaction and over correction to the augment arc in ENT, and how past exchanges like that ultimately lead to federation vs klingon hostilities. Unfortunately Disco didn’t capitalize on this probably cause if they start explaining things they’d ultimately have to admit they can’t get away with haveing the longest heroship in canon…
I’m not really a fan of “it only looks overdesigned cause its supposed to be alien to you!” That they did with early Disco klingons and have done so far with SNW’s Gorn. That line of thinking works for one off antagonists like V’ger, but these aliens are effectively supposed to be recurring characters and and making them and thier ships big balls of (sometimes asymmetric) noise means they all just start looking uniformly chaotic on top of being hard to replicate and recognize outside watching the show.
Externally speaking Starfleet ships march to the beats of NACA/NASA X-planes, Klingon embrace a very soviet yet alien look in contrast, Vulcans look advanced and sleek yet ancient and mythical with the biggest pointiest toys on the block.
Internally speaking construction is depicted as having limits, tech and interfaces are familiar to real world, cramped ship like rooms are the norm, and there’s no handwaving over how everything might fit inside the ships.
