There are different values of "testing" and of "production" - in my
world, at least, they're not atomically defined categories. =)

Would it be reasonably accurate to say "btrfs' RAID5 implementation is
likely working well enough and safe enough if you are backing up
regularly and are willing and able to restore from backup if necessary
if a device failure goes horribly wrong", then?
This is a reasonably serious question.

Thanks for all the info guys.
I ran some tests on the latest 3.12.8 kernel. I set up 3 1GB files and attached
them to /dev/loop{1..3} and created a BTRFS RAID 5 volume with them.
I copied some data (from dev/urandom) into two test files and got their MD5
sums and saved them to a text file.

Can I still run the scrub routing (maybe read-only?) to check for any issues. I
understand at this point running 3.12 kernel there are no routines to fix
parity issues with RAID 5 while scrubbing but just want to know if I
