Actually manipulating higher-degree Bézier curves (or B splines, etc.) is a pain in the butt. In theory you can make any possible shape, but in practice it’s very difficult to get it to do what you want using the standard provided user interface.
> weights of the tangent vectors
Is this a synonym for curvature? In theory you could directly specify the curvature at a knot.
Or do you mean something more explicitly like weights in NURBS? Those could also conceivably be added, but IMO the hit to human intuition / intelligible UIs makes it not worth the trouble.
