It's a tricky problem because "parametric" is a very broad term. You'd need to agree on a full set of primitives, parameters and modifiers and further innovation would be tricky without "baking in" or converting to a less parametric form. Vector drawing software faces a similar problem. There's some agreed primitives but often you just get bezier soup.
