Jujutsu for everyone

I haven't yet given jj a proper trial, so pardon the ignorance. All I've seen are conveniences regarding the working the copy. Besides the subjectively terrible UI, my biggest gripes with Git have to do with collaboration. A rebase may unintentionally overwrite someone's work. A force-push to trunk breaks every other developer's working copy. With "distributed" being in the name of this whole class of VCSes, I would expect that such things just wouldn't happen, but here we are. As I understand it, jj inherits all of these problems and adds better concepts and UI for manipulating the working copy. I'm not sure this alone is a good enough justification for a switch. Of all the Git's features I use a tiny, proven subset and stay on the beaten path. It makes it bearable enough.

Working copy handling differences is certainly an aspect of jj, but, at least for me personally (esp. given me having grown up with git), it's probably my least favorite difference from git. And yet I've moved most of my personal things from git to jj (albeit with a bunch of custom scripts to make the working copy stuff more git-y).

A significant other thing jj does is introduce change IDs (i.e. a (randomly-generated) ID that stays stable even as a commit is amended), with which it should be easier to track changed commits across forks/rebases/edits/pulls/fetches, though I've yet to use jj for collaborative projects to see how much that pans out.

Generally jj makes rebasing things, and generally editing history so much more easy than git, so force-pushes messing with branches is much nicer to "fix" however needed. Being able to leave commits in a conflicted state and resolving only when actually needed also should help.
