Sure. Any objections to the following wording?

```
  /// The name for the split debug info file used for the DW_AT_[GNU_]dwo_name
  /// attribute in the skeleton CU. This should generally only be used when
  /// running an individual backend directly via thinBackend(), as otherwise
  /// all objects would use the same .dwo file. Not used as output path.
