I think the lack of expandable memory is worse than lack of support for dGPUs. Everyone doing technical work (e.g. scientific computing and audio/video and VFX) could use more memory, but not everyone cares about GPU performance. They need to figure out the expandable memory piece first. This would instantly open up the scientific computing market to the new Mac Pro.
