Nope.  See, we deal with what we think we can deal with and what is
impacting the most people.  There are two of us.  A non-default
filesystem with a lot of known issues isn't high on the priority list.
If you would like to see more attention on btrfs, find some people
that share your interest to triage and work on the bugs (which are all
upstream bugs) or chip in yourself.

This isn't a requirement for btrfs by default.  It's a nice to have.

If it's getting close, it's entirely because of Josef's and the SuSE
team's efforts.  They should be applauded.
