This has been false from the very first import of ZFS into FreeBSD
7-STABLE. Pawel even mentions that GEOM allows the use of the cache on
partitions with ZFS somewhere around that time frame. Considering he did
the initial import of ZFS into FreeBSD, I don't think you can find a more
canonical answer. :)
This is one of the biggest differences between the Solaris-based ZFS and
the FreeBSD-based ZFS.
It's too bad this mis-information has basically become a meme. :(
