The question I couldn't understand...what is the advantage of enabling the iGPU? If it works perfectly disabled in F8.
The issue is having the headless iGPU handle hardware based encoding/decoding of video. It's also tied to DRM I believe - which can be addressed without iGPU by using shiki values. In my case, running 10.14.6, I get H264 hardware based enc/dec via my Radeon VII, but with H265(HEVC) I don't. So, any HEVC is being done by the CPU. This comes into play when you're dealing with a lot of HEVC content and you want to take advantage of the hardware you have.
So, if you're not dealing with H265 for encoding/decoding a lot (e.g. speed), then you likely don't care about enabling your iGPU. Of course, we all want to take full advantage of all our hardware, but there are ongoing memory mapping issues for booting with the iGPU. If you run the OsxAptioFix2Drv-free2000.efi memory fix then you can have both, but the author of it says it could have potential issues. So, it's a matter of preference as to which memory fix you choose and if you really want the iGPU enabled.
Here's an image of the settings output from VideoProc. You can see I'm running 10.14.6 and I get no HVEC (H.265) hardware found.
