> But there's the reflog in git which is the ultimate undo tool.

That one sentence outs you as someone who isn't familiar with JJ.

Here is something to ponder. Despite claims to the contrary, there are many git commands that can destroy work, like `git reset --hard`. The reflog won't save you. However there is literally no JJ command that can't be undone. So no JJ command will destroy your work irretrievably.

I’ve just tested that exact command and the reflog is storing the changes. It’s different from the log command which displays the commit tree for the specified branch. The reflog stores information about operations that updates branches and other references (rebase, reset, amend, commit,…). So I can revert the reset, or a pull.

`git reset --hard` destroys uncommitted changes. There is no git command to recover those files. JJ has a similar command of course, but it saves the files to a hidden commit before changing them.
