As I recall, Josef Bacik mentioned that he'd be pushing for Btrfs becoming the default in Fedora 23
 
. At this point, I'm personally convinced that it is certainly ready and doable for F23.

Well actually he said his "plan" was to push for F23.  I've been using btrfs raid 6 for several years now and have been lucky I haven't encountered any issues - but if you subscribe to the mailing list you'll see others haven't been quite as lucky.  I'm sure he'll propose it once he believes it is ready.  When proposing a default change it is prudent to be cautious. In the meantime it's there to use for early adopters; and the more people who test the faster issues will be identified and corrected.  Just be sure you've taken the proper precautions.... ;-)
