From what I understand from reading the list, the only reason zfs has any code that touches disk cache settings at all is that long ago, Sun shipped some drives with the cache disabled by default in the firmware. I think if you aren't using old drives shipped by Sun, this "whole disk" distinction doesn't matter to you (as long as you don't also use UFS, anyway).
