      This metric should be reported for each `vcs.line_change.type` value. For example if a ref added 3 lines and removed 2 lines,
      instrumentation SHOULD report two measurements: 3 and 2 (both positive numbers).
      If number of lines added/removed should be calculated from the start of time, then `vcs.ref.base.name` SHOULD be set to an empty string.
