@wrotki  -- clang formatter did not complain about it. You can see [here](https://github.com/llvm/llvm-project/pull/149238#issuecomment-3084686589) the one place the formatter is mad, and its not complaining about no new line at end of file. The thumbs down was just to indicate that the formatter doesn't care.
