Major Description
The new dimensional points implementations for geo distance, polygon, shape filtering are substantially faster and creates a smaller index than the postings based GeoPointField. They also offer nearest neighbor search, which GeoPointField doesn't.
I think we should deprecate GeoPointField and focus on the points implementations.
We have still other legacy postings based geo implementations but I think we should keep them for now since they have functionality that points doesn't yet have: the ability to index a shape and search for shapes overlapping the indexed shapes.
