With all due respect, Deep Space Nine opened that can of worms the minute Koloth, Kang, and Kor showed up with ridges. I was perfectly happy to overlook the issue until the Tribble episode made a big deal of it. So don't go blaming Enterprise for trying to clean up that mess. ;)
Koloth, Kang, and Kor showing up with ridges was appropriate, not having ridges on Klingons now that it has been established that Klingons have ridges would have made a bigger mess.
That whole episode is a campy "all in good fun" type episode. I thought Worf's "we don't talk about it" comment was an amusing and appropriate wink and nod to the Klingons' change in appearance. Acknowledging the change and brushing it off lightly. But I also think that comment fed a lot of fans uptightness about the whole matter and strengthened their zeal in getting to the bottom of the "mystery" at an in universe angle.
Silly Nerd Trek fans.
