Let me quote what is written there: "We will need to base all our
rendering infrastructure (QPainter, the Qt Quick Scenegraph, and our 3D
support) on top of that layer."

QWidgets use QPainter for rendering.

If you are using OpenGL, RHI won't magically change your code. Use 
QPainter, the Qt Quick scene graph, or Qt3D, depending on your case.
