What about a rotating spare?When setting up a pool a lot of people would (say) balance things around buses and controllers to minimize single points of failure, and a rotating spare could disrupt this organization, but would it be useful at all?
Functionally, that sounds a lot like raidz2!"Hey, I can take a double-drive failure now! And I don't even need to rebuild! Just like having a hot spare with raid5, but without the rebuild time!"
Though I can see a "raidz sub N" being useful -- "just tell ZFS how many parity drives you want, and we'll take care of the rest."
