There’s nothing stopping you from using separate changes to emulate the staging area if you want.

That is, in essence, the "squash workflow": https://steveklabnik.github.io/jujutsu-tutorial/real-world-w...

The big differences are that the jj approach gives you a commit message for the staging change, and lets you jump to some other commit without extra steps.

I can, but I don’t need to.

jj has nothing I need, so it would be changes for the sake of changes. I’m not saying it’s bad, but people do need to realize that their struggles are theirs, not the whole world.
