This is a follow up to https://webrtc-review.googlesource.com/c/src/+/200161 I forgot to actually upload the code that addressed reviewer's comments, and since they were minor comments I went ahead and completed the CL before I realized. Fortunately no harm done because all of this code is behind a disabled build flag. This is a great example of move fast, make mistakes. Lesson learned.
