A very interesting concept. I really like the idea of a "triangles as control" for GPU rendered curves. I think having multiple primitives is less pure but very practical. Too bad you don't get the continuous curve for free like you do in a Bezier curve, but it seems like something good tooling could really help with.

One thing that came to mind: It's pretty easy to encode or include addition points within the vertices of a triangle. So as long as the constraint that the whole section of the curve is contained within the triangle, it might be worth thinking about adding additional control points related to the triangle-control/Gkurve-primitive
