It solves two problems. First is having a batter UI, git is well known to have a bad UI and be hard to teach. But you’re right there aren’t new capabilities.

Secondly, and more importantly, is that you can back it on to different storage mechanisms. Companies with large monotypes are often not using git (Google, Facebook,…), or are using highly specialised git (e.g. Microsoft). JJ is not just got compatible, git is a pluggable storage backend.

I mostly use JJ backing on to Piper, and the integration is excellent. I’ve also used it backing on to git. I can transfer almost all my knowledge and muscle memory between these two places.
