Just for the record, Theodore Ts'o marked ext4 as stable and ready for
general usage more than one year ago . On 25 December 2008 kernel
2.6.28 was released with ext4 considered ready for production. So, ext4
is not _that_ new anymore. One year latter that Fedora 12 and Ubuntu
9.10 began using ext4 as default.
I believe for 5.5 or even on 5.6, ext4 will not be a tech preview
anymore. Considering that RH has extended the support so much, and how
ext3 is so limited with the current and future disk's capacities (fsck
on a 1TB volume is not funny). The current ext4 module is close to the
one on 2.6.29 plus lots of fixes 
 rpm -q --changelog kernel|grep ext4
