Indeed, partitions are disks and wedges appear as a disk that doesn't
support partitions.

You have to set a kernel option. Since changing behaviour is a flag day,
it never happened (actually it happened and was reverted immediately).

It's odd to treat disks differently, i.e. small disks with "physical"
driver names and a partition suffix, large disks with a name (or
an UUID as unique default name).

Make small disks using wedges, indepenent of disklabel or GPT, would
unify both.
