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.

Out of curiosity, did it find a source for those specs that wasn’t indexed well elsewhere?

This change doesn’t even have anything to do with customers as far as I can tell? Sounds like they pissed off their resellers by cutting them out of deals with their biggest accounts, and are regretting burning all those bridges.

Doesn’t look like it, from their docs:
