Also checksums mean I know when bitrot happens. In the worst case (like if you mount the same FS twice, either during hibernation in another OS, or in a VM with passed through disk access) you might get an unmountable FS that the repair tools only make worse. What works well however is btrfs-restore, which can read corrupted btrfs volume and dumps all the files with complete folder structure somewhere else. Why the repair tools are to bad when the restore tool can get everything back is a mystery. But that really only is an issue if you do something retarded like I did. Usually it's rock solid, even after unexpected power loss.
