I really really want a magit version of jujutsu. Apply the same philosophy but use jj commands to achieve it. Under the hood magit still runs git commands so there are still annoyances such as (1) the need to create branches and name them, or (2) having to resolve conflicts as they happen rather then deferring to a more convenient time in the future (first-class conflicts), or (3) the equivalent of `jj evolve` for automatic rebasing.

Also I'll have to say magit simply chose much better names than git. I never understood the `--onto` argument of `git rebase` because it's such a bad name. On the other hand magit calls it rebase subset and it's immediately clear; I now use this kind of rebase almost every day.
