Luckily you can turn it off and use the standard 'add' workflow. I did that almost reflexively when I started trying to use jj. (snapshot.auto-track)

However, over time, and once I got the .gitignore fully set up for bigger projects, I've come around on re-enabling autocommit for more of my repos. It does flow pretty naturally once you have an established process. I find it enables both better 'undo', and more seamless context-switching.

You can also set a more specific snapshot.auto-track on a repo or user basis for personal tooling conventions that don't make sense to gitignore.
