Note that jj is not a frontend for git or an abstraction layer over git — rather, the git object store format is one of at least two backends to jj.

Thanks. That would make me interested in it for a personal project where I only use jj.

There's really no cost to trying it out on an existing project with other people. It natively interoperates with git. Nobody needs to know you're using something different, and you can always fall back to using git commands if you need to do something you haven't learned yet.
