Why use hardware RAID at all if you decide to go with ZFS? Why not JBOD? Cheaper and more reliable (No RAID controller as a single point of failure for hardware RAID.)
ZFS itself uses its own algorithms for software RAID to do what you're suggesting, anyway, so your question is somewhat contrived.
ZFS doesn't automatically remove RAID from the equation, it simply moves RAID into the software level, much like the Linux MD software RAID subsystem.
You can use ZFS on individual devices, but the real benefits come in when when you use multiple disks together in -- wait for it -- a RAID configuration, using ZFS's RAIDZ (or even RAID1).
Sure, the physical infrastructure is a JBOD, but the logical structure is still RAID.
