Sure, my point is just that if you don’t want history re-written, you just don’t re-write it. If you have multiple descendant branches and for some reason you don’t want the children to move as well, you can move them back. It’s almost the opposite of what the article describes; instead of needing to choose to move children, children move automatically and you move ones you don’t want to back. I’ve never wanted to do this but if it happened it would be easy enough to fix.

It looks like this: when a git rebase would pause the rebase to make your resolve a conflict, jj keeps going. When the rebase finishes, if there are any conflicts, they’re displayed in the log with ?? after their ID. jj won’t let you push a branch with conflicts until the conflict is resolved. You can fix the conflict by either editing that commit directly, or my preferred way, which is to make a new change on top and then squash the resolution back in after you read it over.

So there’s a few thins about why this is useful: because children are also rebased, you can see immediately how much work, if any, you have to do. I have an alias to rebase all open branches on top of trunk, and will often pull trunk, run it, and see if I have any work to do to update them. “Oh, only one of my three branches needs work, I’ll work on the two that are fine first” can happen, and that third can just sit there. Or, as I said before, I could move it back on top of its old base, and the conflict disappears. Or, say I suspected none of them conflict, but all three do, and I don’t want to do it at all right this moment, I’ll just jj undo and they’re all unconflicted and back in place.
