If a polygon is smaller than the largest polygon in our dataset of
simplified polygons then we’re only throwing away useful detail by
simplifying it.
We should still simplify larger polygons as a fallback, to avoid sending
anything to the CBC that we’re not sure it will like.
The thresholds here are low: we can raise them as we test and experiment
more.
Here’s some data about the Flood Warning Service polygons
