Clearly the partitioning layer is redundant whan the disk is not a part of root pool or dual-triple-boot configurations. However, you can use LUKS containers underneath, or you can use Ecryptfs for the entire filesystem, which would still give you all the checksum, scrubbing and data integrity benefits of ZFS.
