Do you mean the person that added `CLOption` to these flags? That was @tarunprabhu, but IIUC that was by mistake; his intention was to extend these flags only to Flang.

Otherwise `-Xlinker` has been around for very long. I guess I will revert these flags to be clang and flang only, then open issues for the discussion of potentially enabling them to clang-cl.
