Meanwhile, just for reference, ZFS started in 2001. Introduced in Solaris in 2005 and FreeBSD in 2007.
I'm not necessarily trying to make a point here, just adding some related facts.

I don't know if it's fair to say that ext4 "started" in 2006, given that it was an evolution of ext3, which was an evolution of ext2 (which I assume was an evolution of ext?), to the point that you can still mount an ext2 filesystem as a very feature-limited ext4 filesystem.
Why the 7 year gap for stabilization? Especially after ext4 only took 2. Jusding from the timelines, btrfs is much more complicated and I'd guess more Linux users exposed more corner cases, but a 3.5x lengthening is substantial.

AFAICT, btrfs is a while new system, while ext4 is a set of changes to an already tested coffee base.

*code base. Friggin' autocomplete.
There is no magical point in time where a file system is suddenly "mature". If anything I'd argue once OpenSUSE started defaulting to it one should consider it stable. I just wonder why Ubuntu / Fedora are not prioritizing making it default since snapshotted upgrades are such a huge usability gain and are trivially easy with btrfs.
