As mentioned in that topic, it’s not that simple. For exampling tweaking a parameter in geometry nodes might cause an object to be generated, or changing a driver value somewhere might cause a collection and associated objects to become visible.
Renderers can not integrate at the level of user-edited data, they can not reasonably understand how that relates to the evaluated scene.
Sure, I get that this is impossible now; I apologize if I sounded like I’m demanding this be implemented now. @JuanGea did ask what third-party render engines would like to see improved in Blender’s code, and this one of the things I want.
