Sounds more like just adding a ton of wasted time for the reviewer to read through those discussions. At least summarize it yourself, e.g. "After discovering manpage XYZ, it became clear that the correct usage of this function is fooBar()".

Why would the reviewer need to read through discussions? The description + code should be just fine.

It's like having someone watch a livestream screen recording of you writing the code.

It's nice to have there IF you need to go back and learn something, but hardly a review requirement.
