> because there's no single thing that you can do with jj that you can't with git. - jj undo, jj op restore, and jj --at-op to reset or view the repo at a previous state - create multiple directories (workspaces) backed by a single repository at different commits These are the only things I can think of off the top of my head that you can do with jj that you can't do with git.

> to reset or view the repo at a previous state What about `git reflog`?

  That lets you see previously checked out revisions. Jujutsu keeps track of all previous repo state. In git, you can pull a new remote branch, delete that branch, and push the deletion. If you want to get that branch back, git reflog will only save you if you checked out that commit. If you didn't, you're SOL. Jujutsu will let you undo the delete operation, restore the repo to a state where the branch existed, or view the repo at a state where the branch existed, and create a new branch at the same revision that the old branch was before it was deleted.

    This is interesting, thanks!

    That might be cool, actually. FWIW, I cheated on a previous job for months by working 10% or so, then faking git commit data to spread it out across the week before sending a PR. Thank you "git commit --amend --no-edit --date xxx"

    What if you commit secrets to the repo by accident?

      Just edit it out and don't push it to upstream?

      Jujutsu repos only exists locally. There are no Jujutsu remotes, only git remotes. Repo properties unique to Jujutsu (repo history, stable revision IDs) are not pushed to git remotes.

> create multiple directories (workspaces) backed by a single repository at different commits This is `git worktree`. They don't work with submodules but submodules are a disaster that should be avoided anyway so probably no big loss there.

  Ah, I was not familiar with that feature in git. In that case, I'll swap out jj workspaces for sparse checkouts :-)

    Apparently git sparse-checkout exists! I'm going to stop guessing features that git doesn't have now.

> jj undo Yeah - the other day I did a fetch, and then decided I didn't want to fetch. I simply ran "jj undo" to undo the fetch.
