By the way, I appreciate how openstreetmap-carto renders boundary
centroid labels in a different, less prominent manner than a place node
that may happen to be part of the relation. This reminds me of how print
maps in the U.S. take one of two approaches to labeling municipalities
that correspond to human settlements:
* Label the cultural or commercial center of a city very definitively
and simultaneously place small labels along the border as space allows
* Plaster a fainter, watermark-like label stretching across the
administrative area, without implying that the label is centered over
the city center
The latter approach also works well for any kind of administrative area
that isn't built up around a specific location. I'm glad the data model
can support both approaches, even if the naming of the "label" role has
proven misleading. Hopefully more renderers can consider these options,
which avoid the perception of duplication.
