It's a matter of taste, but I much prefer the workflow in the tool I hacked together for this, https://github.com/jlebar/git-pr-chain.

In the tool I wrote, you have a single branch with linear history. PRs in the chain are demarcated via commit messages. You then don't need any special rebase / sync commands -- you can use regular `git rebase -i` to reorder commits or edit a commit in the middle of a stack. Literally the only special command I need is "push this branch to github as multiple PRs".

Anyway I hope that alongside the branch-based you've built tool in `gh` that there will be an API that I can target.
