Thank you for working on this check!
Please, read comments on previous pull request https://github.com/llvm/llvm-project/pull/99713.
I think there could be some improvements done based on comments in that PR.
For moving this check to `readability` section script `clang-tools-extra/clang-tidy/rename_check.py` can be useful.
