I get the feeling that depends on who you ask at this point, but there has apparently been some recent development of the hosting platform (https://nest.pijul.com/). I don't know if it can have as good of a Git interoperability story as, say, jj.
I am not interested that much in interoperability with Git.
But I am afraid of data corruption, crashes, etc.
Also, Pijul used to have severe performance problems in some situations.
I would call it ready for production if it is stable and performant.
Git interoperability can help with that: if you have an on-disk data format that's either compatible with git, or can easily be converted to git, you can keep your backups in git format, and work from them with git if something goes wrong.
