The issue with composition is only a problem when you rely on a pure text prompt, but has been solved for quite a while by ControlNets or img2img. What was lacking was the integration with existing art tools, but even that is getting solved, e.g. Krita[1] has a pretty nice AI plugin.
3D can be a useful intermediate when editing the 2D image, e.g. Krea has support for that[2]. But I don't think the rest of the traditional 3D pipeline is of much use here, AI image generation already produces images at a quality that traditional rendering just can't keep up with, neither in terms of speed, quality or flexibility.
