Yes, the initial release of bootable zfs has restriction on the root
pool: i.e.
no concatenation or RAIDZ, only single deviced pool or a mirrored
configuration.
This is mainly due to limitations on how many disks the firmware can
access at boot time.

I've not noticed any posts since that modify its content.
That would be too bad if raidz is not supported. I have been running a
server with "bootable" zfs (3 disk w/raidz) for the past 6 months (1U
server).
I've simply been using the trick that tabriz posted on her blog a while
back, but I lost only a small amount of space on each drive by using a
USB drive for the initial install and putting grub on its own.
Performance is not earth shattering due to (I think) /var/tmp
and /var/log. And it's old ZFS code. I've not rebooted or upgraded since
then.
