Yes, I've been waiting for a real breakthrough with regard to 3D parametric models and I don't think think this is it. The proprietary nature of the major players (Creo, Solidworks, NX, etc) is a major drag. Sure there's STP, but there's too much design intent and feature loss there. I don't think OpenSCAD has the critical mass of mindshare or training data at this point, but maybe it's the best chance to force a change.
