Good point. There should be at least 1 partition per disk and if I have fewer partitions I'm limited to how many disks I can use and won't be able to increase my cluster.
I'm currently hard-pressed for performance and the capacity (upper limit rather) is known. In my case, I'm inclined to take the performance benefit even if that means I can't grow my cluster.
