+1

I tried enabling SU+J on my /var (after backing up of course) and after 
a panic random files were missing entirely. Not the last updates to 
those files, the whole file, and many of them had not been written to in 
days/weeks/months.

With all due respect to the hard work that went into the code, I would 
be very uncomfortable with enabling it by default at this point.
