I'm not quite sure about that but I think these kind of TODOs should be done in separate PRs. 

For example I have one here waiting for Clang 20: https://github.com/llvm/llvm-project/pull/101826

I think this PR should be just about updating the CI and not fixing all unrelated TODOs. Please check what was done in the past.
