The layout changed when the radius property was added to shape keys in 2.8, but the RNA code wasn't updated. Also, even before that, the code didn't do anything to correctly handle mixing sub-curves of different type (nurbs vs bezier) in the same Curve object. Now that case is handled correctly but not very efficiently by allocating a mapping table when necessary. To recover some performance, a custom index lookup function is added.
