Yet that's exactly what the wiki suggests: "If you have a broken filesystem, it is probably better to use btrfsck with advice from one of the btrfs developers, just in case something goes wrong. (But even if it does go badly wrong, you've still got your backups, right?)"

I think it's understandably annoying that the repair tool could make things worse rather than fail gracefully, because restoring from backups is tedious. But the only way it gets better is if people break both the file system and the repair tools in ways the devs can't possibly predict.
