That makes sense, good to know, thanks.

> I basically always force push

How do your colleagues deal with this, or is this mostly on experimental branches or individual projects?

JJ has the concept of "immutable changesets" -- if it sees a commit is referenced from a branch that it's not tracking, it assumes it ought not rebase that commit. Changesets on branches that look like the main branch are immutable too. And you can edit the revset that JJ considers immutable if you need it to be different from the default.

The net effect is that I can change "my" branches as I wish, but I can't change stuff that's been merged or other folks' branches unless I disable the safety features (either using `--ignore-immutable` or tracking the branch).

JJ also makes it really easy to push a single changeset as a branch, which means as you evolve that single commit you can keep the remote updated with your current work really easily. And it's got a specific `jj evolog` command to see how a specific changeset has evolved over time.

It's generally fine if you force push a branch that you're the only one working on. In many projects, there's an expectation that the 'PR Branch' you create in order to make a github pull request is owned by you, and can be rebased/edited/force-pushed at will. It's very common to do things like `git commit --amend --no-edit` to fix a typo or lint issue and then force push to update the last commit.

This has it's problems, and there's a reason things like Geritt are popular in some more sophisticated shops, as they make it much easier to review changes to PRs in response to reviews, as an example.

The PRs are either small enough that it isn’t a problem or large enough that it isn’t a problem… the odd in-between PR experience sucks and it’s one of the cases when I sometimes add more commits instead of force pushing.

+1 to sibling gerrit recommendation; I used to use it a decade ago and it was better then than GitHub PRs today.

People barely ever work off my branches.
