Raidz wasn't able to be expanded in place before this. You were able to add to a pool that included a raidz vdev, but that raidz vdev was immutable.

Oh ok, I've never done this, but I thought it was already there. Maybe this was the original ZFS from Sun? But maybe I just remember it incorrectly, sorry.

I've used it on multi-drive arrays but I never had the need for expansion.

You could add top level raidz vdevs or replace the members of a raid-z vdev with larger disks to increase storage space back then. You still have those options now.
