Comment(by cremona):
This is a good idea. When we implemented the one-line test for
nonsingularity of general curves over finite fields last year (after
discovering to our surprise that it was not implemented) we did not think
of this special case. The generic is_singular() method is defined in
sage/schemes/plane_curves/projective_curve.py as a method of class
ProjectiveCurve_generic. Your H is of a derived class, so it would be
possible to write a different is_singular() method for that subclass.
