I believe the answer is in the last email in that thread. hald doesn't offer the notifications and it's not clear that ZFS can handle them. As is noted, there are complications with ZFS due to the possibility of multiple disks comprising a volume, etc. It would be a lot of work to make it work correctly for any but the simplest single disk case.
