It's about resourcing and stability. Oracle only employ one person (AFAIK) on btrfs -- Chris Mason. He does a sterling job of maintaining and developing the filesystem, but there is only one of him. Since well before December, he's been working on a functional fsck, trying to get it to a state where it won't demolish your filesystem even more than it already is. This has left the work to integrate the RAID-5/6 patches behind. He's also been working hard on fixing a great many other stability issues as they're reported, and integrating patches from other developers. I believe that RAID-5/6 is the next major piece of work that Chris is intending to integrate, once fsck is ready. However, stability is better than features at this point. I don't see any commercial benefit in preventing the integration and deployment of the RAID-5/6 patches, but simply that there's other things that are more important. Please be patient.
