I think that sounds right. If Simple is on, you must have all the handles (if I remember right that showing them is necessary to get good continuity)
One of the drawbacks now is there is not a way to get a shape change spread across the entire span along the edges and also get good continuity - that is, show no interior handles and modify the handles at one end and have the resulting shape blend or interpolate smoothly along the edges, and get good continuity. If I am right about that it seems like a step backwards.
I think there should not be a scenario where it is possible to get continuity less than what is asked for.
I’ll think some more, it’s good for me.
