No, they were imported. The import left them all on the extreme
eastern and often southern corner of the county. I have moved a lot of
them to approximately the center.
I think the reason they exist is the same reason why cities always
have a node in addition to their administrative boundaries. And
states/countries too far that matter. Most renderers render the name
from the nodes, not the admin boundaries. The reason I started moving
the county nodes is that I saw the county name labels were in odd
locations on Mapquest Open. Not saying this is ideal... but that's the
way things are at the moment.
But most features do render from boundary ways/relations. So in the
case of parks, definitely only the outline is needed.
