I was motivated to deprecate num_points and crs because number of GEOSGeometry members looks disturbing for me.
In [2]: GEOSGeometry.
In [2]: from django.contrib.gis.geos import GEOSGeometry as Geometry
In [3]: Geometry.

I'll change ticket summary because there are also getters/setters for coordinates of Point and probably there are others.
