Yes, they are supported, and documented at https://github.com/martinvonz/jj/blob/main/docs/branches.md https://github.com/martinvonz/jj/blob/main/docs/branches.md. I need to document better how to use them for common workflows like GitHub PRs. FYI, here's one way to use them with GitHub PRs: 1. Create a fork via GitHub's web UI 2. Clone using the SSH protocol (`jj git clone git@github.com:...`) 3. Make your changes and "commit" (`jj close/commit`) 4. Create a branch pointing to the commit you just created (`jj branch my-feature -r @-`) 5. Push it to your fork (`jj git push`) So that doesn't seem too onerous, I guess? Maybe the "too many manual steps" are to clean up afterwards. I just tried it in a test repo and deleting the branch from the fork and then `jj git fetch` from there does delete the local branch, but it doesn't abandon the commits, so you need to run `jj abandon` on them if you don't want them anymore.
