as it turns out raid 5 and 6 being broken is kind of a big deal for people. its also far from ideal that the filesystem has random landmines that you can accidentally step on if you don't happen to read hacker news every day.

FWIW: RAID 5 and 6 having problems is not a random hole you'll accidentally stumble into.

The man page for mkfs.btrfs says:

> Warning: RAID5/6 has known problems and should not be used in production.

When you actually tell it to use raid5 or raid6, mkfs.btrfs will also print a large warning:

> WARNING: RAID5/6 support has known problems is strongly discouraged to be used besides testing or evaluation.
