Do you happen to know if there's a linux filesystem that has bitrot protection, but doesn't need snapshots?

- ZFS is not in the Linux kernel so I don't want to use it for a daily work machine

- btrfs works fine but its tools to undelete/recover files when something did go wrong are pretty bad

- XFS looks ancient, not sure how good it is

- ext4 is also pretty aged by now, but is what I use now after my attempt at btrfs. It doesn't have any bitrot protection though

Is there anything else viable today? The above are basically the same choices as I also had 10 years ago
