To be fair to btrfs, that's it's USP compared to ext4 - when hardware fails, it lets you know that your data has been eaten at the time of the issue, and not months down the line.

And knowing consumer hardware, chances are very high that it did commit everything properly, and then had a catastrophic failure when there was a surprise power-down. Unfortunately, unless you have an acceptance lab verifying that kit complies with the intent of the spec, it often complies with the letter of the spec (if you're lucky) and no more :-(
