Except that partitioning a single device completely falls apart when using ZFS, as zpool is designed to manage entire drives, and managing multiple partitions as vdevs on a single device would not only kill performance, but severely imperil data redundancy. Once the drive kicked the bucket, all the vdevs would be gone too, causing an outage.
