​Interesting workaround! It is "reasonable" since the hull operation
depends only on the vertex positions. So, missing facets in a polyhedron
are irrelevant.
For instance, this code renders fine:

intersection(){
  hull(){
    polyhedron( points=[[0,0,0],[0,10,0],[10,10,0],
                        [0,0,10],[0,10,10],[10,10,10]],
                faces =[[0,1,2],[3,4,5]]);
  }
  sphere(8);
}


​If you drop the hull, CGAL complaints.
