I would like to use it for the new utility - https://reviews.llvm.org/D86539#inline-1182993 . I think it would be good if the behavior would match with  "objcopy". f.e. this utility might be used instead of

  `llvm-objcopy` --only-keep-debug in-file out-file.debug
  `llvm-objcopy` --strip-debug in-file out-file
  `llvm-objcopy` --add-gnu-debuglink=out-file.debug out-file
