Right, but those are unrelated to this PR. We are basically aiming for the final PR from the feature branch to branch-23.04 to pass.

Just one question this PR title says we're dropping the names and dtype kwargs for Index.copy but I also see changes dropping levels and codes from MultiIndex.copy, is this as intended?
