One nice feature of git-branchless (I'm the author) is in-memory rebases. For example, the `git sync` command will rebase all local work on top of the main branch without checking out those branches. (It will also not start merge conflict resolution unless you pass `--merge`, which makes it a lot "safer" to frequently rebase your work.) This helps a lot to avoid invalidating builds.
