Some even if the MBR doesn't contain the correct magic partitions for
sleep/save images and the like.

Long way or short way, MBR is not optional on the first disk on the
PC architecture and consequently we should not try to hide the fact
that it is there.

For all other disks, people can usually label them as they like,
(now including: "not at all") and GEOM will name the resulting
devices in an intuitive and consistent way.
