Well, like I said, I don't think ENT's explanation is the best possible explanation, Klingon-wise. But it's still an improvement over what we had before.
Pretty much. And at least the ENT explanation used both of the theories postulated by O'Brien and Bashir when they questioned Worf on DS9. It answered the question, solved the mystery and also gave a respectful nod to DS9, a series that never even had an Augment Klingon before Season 5 and would never show one after that.
