I believe it is possible (with or without the patch) to boot purely off
of ZFS.  The ish.com.au document describes how to do this in "Step
Three: solving the ZFS boot problem".

I simply choose not to utilise that method.  I'm a bit paranoid about
non-UFS root filesystems.  My main concern revolves around booting into
single-user, which is an important part of the whole build/install world
process -- does it actually work with ZFS as a root fs, and if so, is
any sort of craziness required to accomplish it?
