SAABs have them too -- at least my 89 900 did. The SAAB includes a
little hanger, not as a separate tool, but as a permanently attached
little peg between two of the bolt holes, and the wheels are machined
with a matching little hole to hang the wheel on. The wheels are
also hubcentric, so once they are hung and pushed over the hub, the
basically stay put while you put the bolts in.
As for motivation, I note that the threads on bolts are protected
from the elements, and the exposed threads on studs are not, wheel
covers and hubcaps notwithstanding.
