I use git but I instead just keep all PRs stacked on top of each other and rebase when one is merged. If something is easy to review I push it down the stack. If something is harder to review I keep it at the top of the stack.

I don't open a PR for each commit, and we use squash commits at work which makes it harder to have this workflow but it still works fine for me.

I rebase only the leaf PR, and I have update-ref enabled to update the branch refs of all other branches in the stack. It works well. The only manual process is that I have to manually force push each branch afterwards.

Lastly, I use the `-x "cargo fmt" -x "cargo clippy"` feature when rebasing (which is missing in jj) to make sure the stack stays in a good state
