If by "Solaris" you mean some fork of Open Solaris, that's quite possible.  
I think that they are all downstream of OpenIndiana.  My impression of 
that community is that they are having trouble keeping up.

My guess is that you are attracked by maintained forks of Open ZFS.  
Subsequent developments of ZFS by Sun were not made available to Open ZFS

I used to work on the Solari:

 Illumos is current, with the best distro (in my biased opinion) being Helios, as used on the Oxide machines. The company has a lot of ex-Sun folks and seems to be ahead of Illumos in several areas. .

Fred Weigel will know more about ZFS, he was one of the maintainers on BSD.
