Just out of curiosity. What’s the downside of using iMacPro1,1? I haven’t seen any issues so far - no kernel panic no nothing.
Using the iMacPro1,1 SMBIOS is the only way (AFAIK) of using your dGPU for H264/H265 video encode and decode instead of a "Headless" IGPU configuration, DRM also tends to work much better with the the iMacPro1,1 SMBIOS.
The only real downsides to using the iMacPro1,1 SMBIOS are :-
1. Some systems don't get full native CPU Power Management as the iMacPro uses a XEON W based CPU, as such the iMacPro1,1 SMBIOS is optimised for XEON CPU power management which differs to standard Desktop Class CPU's. In most cases it is possible to remedy this problem by installing and configuring "CPUFriend" :-
Dynamic macOS CPU power management data injection. Contribute to acidanthera/CPUFriend development by creating an account on GitHub.
2. It is impossible to use the SideCar feature in Catalina. A real iMacPro uses its T2 chip for hardware compression/decompression of the iPad video/data stream. The only way to resolve this issue is to use a non-pro iMac SMBIOS and configure the IGPU for compute only use by means of a "Headless" platfrom ID.
