I disagree with the people saying "never use edit". There are plenty of people saying conflicting things about git too, and I'd argue that understanding edit versus new isn't anywhere close to the level of wart that having to get people to agree on merging versus rebasing. Like you said though, have fun with that!

jj has far fewer warts than git. You don’t have to learn every jj idiom, you just have to find a workflow you like, which you will, quickly, because it’s so easy to use. Personally I don’t know why anyone uses `edit` but if they like it then I’m happy for them.

No system is perfect, but there's nothing wrong with `jj edit` and `jj new`. Both commands are completely reasonable and do what you think they would do.
