"taking the index further" deprecated?

https://jwiegley.github.io/git-from-the-bottom-up/2-The-Index/2-taking-the-index-further.html

The section is showing its age. I doubt many are going "Quilt!" while reading these days. Also, `stg` doesn't really offer much afaict on top of just `git stash push`.

Would a PR for dropping the section be accepted?
