Yeah, as Byrne once describe it, "Every time Superman celebrated a Kryptonian holiday or performed a Kryptonian custom, it was like he was spitting on the graves of Ma and Pa Kent." He said it reminded him of those people who insist on referring to themselves as something-Americans and not just simply Americans.
So he made the rather clever move of making Krypton a sterile, lifeless world that no sane person whose customs no sane person would ever want to emulate, nicely circumventing the whole problem.
