Related to https://github.com/maplibre/maplibre-style-spec/pull/519 and https://github.com/maplibre/maplibre-gl-js/issues/3516 According to the Style Spec, `["geometry-type"]` is expected to distinguish between LineString and MultiLineString, while `"$type"` does not. For the transportation layer, the distinction is harmful. All of OMT style layers, except these two, use `"$type"`.
