The script in -current does not use any code from the link above. The script in -current does not do snapshots, only scrubs. The script in -current does only do "zpool list", not "zfs list". So all in all, the script in -current does not need any change (I would have preferred the "-t snapshot" way of listing snapshots, if it would have been necessary).
