yeah, i saw it. Main reason for me "toying" with btrfs is my work. We
rent Linux servers to customers. While they install and manage them by
them self, there will be questions about btrfs to our support, sooner or
later. So getting your hands on it early saves some headache later.

It is just inconvient for me now, so no big deal.

I first tried degraded, I also tried repair, no luck.

What I do now is, getting as much data from the broken fs with btrfs
recover and do a rsync after. It is just faster then downloading all
the data from my own mirror in the datacenter. ;)

After that I will even be so crazy and try it again. Next on my list is
send/receive.
