Apart from that
I think it's a good idea.

As a consequence, the /tmp, /var, and swap could eventually be moved
to the ZFS hard drives to greatly reduce I/O to the CF card.
Or zfs's slab logic could have a randomized block selector where every
write to the cf device gets written to a random free block instead of the
disk based weighing that is done now.
Most flash devices have wear leveling builtin, so I'm not sure that adding
this feature to ZFS will accomplish much. IMHO, the more important ZFS
feature, wrt flash, is COW.
BTW, CFs can do a large number of random iops, much larger than any disk.
