You'll be the first to know when I write it. However, if anything, GitHub sort of killed the mailing list as a generally viable collaboration format outside of very specific use cases, so I'm not sure if I'm the right person to do it justice. However, it is a very cool and unique format that has several benefits that GitHub PR based workflows really lose out on.

Also, in a PR, I find that people just switch to Files Changed, disregarding the sequence of the commits involved.
This intentional de-emphasis of the importance of commit messages and the individual commits leads to lower quality of the git history of the codebase.
