btrfs roadmap

Hello, how far or how close we are to some stable release (I assume that would be 1.0) ?

I was looking for some "detailed" timeline, but I found only this link
http://btrfs.wiki.kernel.org/index.php/Development_timeline

... but I was looking for something like ubuntu has
https://wiki.ubuntu.com/LucidReleaseSchedule

...it would be great if ubuntu 10.04 ships with btrfs 1.0

... "If we manage to work fast enough to add installer support for Lucid, it will not be presented by default, as it is not clear that the filesystem is stable enough yet...",
https://wiki.ubuntu.com/FoundationsTeam/BtrfsSupport

cheers,
rk
