Hi Marco, instancing is very much on my radar! I never meant to say it would never come, just that I don't know yet when it will happen. Not for v4 though.

I think that probably hierarchy, grouping, and instancing will need to be all considered together in order to go in a good direction. It will take quite a lot of planning.

Previously I had been thinking that maybe groups would go inside the "Objects" section of the Scene browser along with named objects and that instances would have a separate section. But I've been wondering if it might be better for them to all be intermingled in the same section and that you could filter the view to see just instances for example.

One other kind of hierarchy that will probably be less complex to implement will be to have folders in the Styles section. That will be a lot less complicated so it's likely that will happen first.
