Does not matter how many and Trill are not the only race to get revamped.
You know what, there's a degree of subjectivity to what will annoy people and not. The Trill don't annoy me (I think the DS9 look is better and I have no problem assuming two racial variants in this case for some reason), while the DSC Klingons do (I think it's has to do more with the behind-the-scenes reasons and lack of having old Klingons also represented).
They went with GR's idea from TMP, and one TNG kinda went with and got more and more armored as the shows went on. Really, hair never fit the lore other than a single line that used it. It was simply used as well "everyone has hair!". I would have left the hair myself, but I don't hate not having it and do not find it a major issue in any way.
The TMP Klingons had hair, too, as I recall. (It became kind of a signature look for them -- long hair and a beard, which may be why the DSC ones look so odd to some of us; try imagining a
Star Trek show where the Borg use sleek white and silver Apple-like technology instead of the kludgy black cybernetics we all know.)
Let's not dredge up that debate again (if them being "non-canon" simply means that they can be overwritten at a moment's notice, I don't find that status being very meaningful since that's how DSC is treating genuine canon materials as well, but to each their own). In any event, tie-ins are supposed to be canon compliant, so having a hairy Klingon in a DSC comic means that it's considered consistent with the TV show, which means that DSC fits with the rest of the franchise at least on that point.
I really think the easy fix is the argument virus if they are gonna keep that horrid storyline. Those with hair re arguments or have argument blood in them.
Since ENT (and the post-TOS programs) showed that non-affected Klingons had hair, I don't think that would work. At best, a hairless subspecies would be the way to go if the DSC Klingons must be bald by biology.
Or hell, the Bald could be the current "fashion" or as simple as not all ethnicity have hair. As someone who shaves his head, its a minor thing to me
I prefer that explanation over the behind-the-scenes reasoning, since it would work with canon (only raising the question why we've never seen TOS Klingons, old ridged Klingons, and DSC Klingons onscreen together and each type seems to be the vast majority in each case, but that's I think that's fair to ignore given the real world reasons). At the end of the day, I've come to conclude that the Klingon makeup itself can fit as is right now (even if I feel that the reason behind it existing in the first place proves that the Powers That Be are not following their claims to be keeping to canon). Frankly, at this moment, Lorca's Horta is my main pet peeve, given that that is a direct canon violation for no good reason with no good answer. (Is Lorca's Horta actually a real Horta -- or just an Easter egg that's "really" supposed to be something else? The
Memory Alpha Wiki says nothing about DSC on the Horta article.)
