You actully do unless you want to lose significant chunks of your disk space.
The Sun disk label only allows you to specify the start of a partition in cylinders, so if you want to use a filesystem like XFS you have to start the partition on cylinder 1 which can be many blocks into the disk. That entire first cylinder is completely wasted.
What XFS does by putting the superblock at zero is simply does not take these kinds of issues into consideration.
