As a recently retired Systems Architect, having served over 35 years in two global IT services companies, specialising in Networks and Systems Security, anything that compromises my system's security is a Bad Thing. I have found that there are very few things that OpenSCAD, as a 3D modelling tool, does badly, simplicity is good, complexity is a loophole waiting to happen. As a 3D generative engineering tool, it can be more challenging to create objects using OpenSCAD that are structurally sound [no sharp internal corners] and look 'right' , but the wonderful libraries and community contributions go a long way to fill in the gaps. One question, if a pair of objects can be mesh filleted using Python computations to create the image in Sanjeev's email,  why does OpenSCAD need Python support at all? Fillets, so beloved of cast-iron foundries, are one of the elements which OpenSCAD could improve, but I'd like to thank all developers of OpenSCAD for creating something a mathematical numpty like me can use productively  without resorting to mind bending computations to create something useful.
