I dont think there are any specific plans at present, as its not deemed
stable enough. Its also a complete resource hog compared to ufs, so for the
foreseeable future I can't see it happening.

One of the good things about freebsd is the range of hardware it supports.
If you made zfs the default option you would be making most hardware over a
few years old unusable without tinkering with the default options.

However  two or three years (ish)  when the average new purchase its a 16
core system with 16 GB ram, a few ssds and 10 TB of disk and the older
systems are the hi spec systems from today then there would be a good case
for it i guess.
