Rebase is incredibly useful for me because I commit on every save and squash my commits before submitting for PRs (if working on a team). I commit on every save for three reasons:

1. I can easily undo small mistakes this way,

2. It makes it easy for me to pick up what I've done the last time I worked with that codebase, and

3. It makes it easier for me to tell a comprehensive story when I'm ready to submit my PR.

That said, I do see the authors point about rebasing onto a branch with dependencies.
