Yes, canonical was brave enough to assume they don't need DKMS for zfs.ko ... [1]
From my experience, Ubuntu's ZFS support is pretty solid, even for root disks. There were some limitations in the past, however - for example, you might not want to use ZFS on a ssd root because of its write amplification.
By the way, there's a handy PPA with newer versions [2] - but this does use DKMS.
