Agreed. Especially the ability to split an object into multiple components/traits and have an operation run automatically for every component type appeals to me

Agreed. Especially the ability to split an object into multiple components/traits and have an operation run automatically for every component type appeals to me. It just seems elegant and 'good design', similar to 'composition over inheritance'. I think the strength of the scene graph is in the explicit parent-child relationship, where it applies, but I probably need a deeper understanding than I now have to mesh them in the right way.
