The patch fixed GPT/ZFS booting for me, too. It would be good to have
it in 8.0 (since it is definitely required to boot from ZFS pools with
non-trivial sizes), and does not affect anybody not trying to boot
this way. OTOH, it since you cannot just install FreeBSD on pure ZFS
from sysinstall, it might be sufficient to prominently warn about this
problem and point at the required patch, to prevent foot-shooting.

But having this patch that has been successfully tested by a number
of people that suffered from the GPT/ZFS boot problem looks highly
preferable to me ...
