If there's any indication that it's not reliable then it'll be reverted before release.

"Note that Btrfs does not yet have a fsck tool that can fix errors. While Btrfs is stable on a stable machine, it is currently possible to corrupt a filesystem irrecoverably if your machine crashes or loses power on disks that don't handle flush requests correctly. This will be fixed when the fsck tool is ready."

(From the btrfs homepage)

That alone should mean the feature should be postponed; unless the Fedora developers know more than us and that (now quite delayed) tool will be released within the next six months?

If you read the IRC meeting logs and earlier conversations in Fedora devel list you would already know the answer to this. Josef Basik, Red Hat Btrfs filesystem developer is actively working on this upstream and he claims this will be released shortly after extensive testing. If this doesn't hold true, Btrfs won't be retained as default for the final release of Fedora 16 as FESO has already stated clearly.

If your device isn't handling flush requests properly you should fix/replace the device. I also suspect that misbehaving devices are relatively rare after seeing that vendors like HP/Compaq/EMC specifically tested for that in their qualification tests for disk drives. The whole idea of those flush commands is to ensure that data has been written persistently.
