We can't distinguish between geonames of different layers due to an
ambiguity in our Elasticsearch schema that we unfortunately won't be
able to fix for a few weeks.
So, while it's technically true that there are countries, cities, etc
contained in the geonames dataset, it's still better for now to remove
geonames from these layers. We have good coverage of most coarse layers
from quattroshapes alone, so the impact isn't too bad.
