Anyone know why it took so long for an on-board GPU and GPU card to finally work together instead of always having to choose one or the other?

Not sure what you exactly mean here. You could use even something as advanced as hybrid crossfire on AMD's 780 Chipset almost ten years ago.
I think s/he's referring to mGPU? As far as I know, only the developers of Ashes of Singularity (Oxide) has shown an iGPU and dGPU working together in mGPU configuration. Since I believe it requires a lot of developer work I don't see this feature being used often...
1. DX12 implementation has been patchy at best, so far we have only seen very few games that uses DX12 from the ground up, and only 1 uses that mGPU feature: Ashes of Singularity
2. GPUs these days are so much more powerful than any on board GPUs that unless you have a really low end GPU (like a 750ti or lower), you are unlikely to see a massive improvement over using the dGPU alone. I am a minority, but my 1080 would be so much more powerful than my 4790k's iGPU that it would not yield enough of a performance boost to risk the CPU throttling.
3. Quite a number of devices these days only have one or the other, but not both. None of the Ryzens and extreme CPUs have iGPU, and a lot of portable devices only has iGPU.
Basically, I am of the opinion that, while it sounds GREAT on paper, in practice it most likely won't fly. AMD/nVidia GPU mixing will have driver conflicts to worry about (assuming neither driver implements 'features' that gets disabled or disables GPUs when it detects the other side), and iGPU are still too weak to make an impact, and most likely will continue to.

Most places provided tests that paired an AMD dGPU with an NVIDIA dGPU. The only place I found adding the iGPU into the mix was WCCFTech, and adding the iGPU with a more powerful card actually hurts performance.
