Saying ther is `no reason to' is maybe too strong... it is not a
mandatory thing to do, but there are reasons some people might prefer to
have partition tables (e.g. to use them as a kind of `label' to show the
disk contains LVM data, the partition table provides some very useful
clues like this in situations where hundreds of LUNs exist)
