Infinity Fabric Link with Premiere Pro on Mac Pro

I've been thinking of upgrading my Mac Pro with another Pro Vega II GPU, for use with various 4K/8K video projects in Adobe CC. Mainly working with a lot of 10-bit 4:2:2 XF-AVC, Red Raw, Canon Cinema Raw Light, etc. A good mix of media codecs. Color grading mainly through Lumetri Color, but use various GPU-accelerated effects and plugins like NeatVideo.

I've been researching the Infinity Fabric Link that comes with having 2 of the same MPX GPUs in the Mac Pro, but can't seem to find too much information on its usage. I see that it provides a far faster interconnect between the 2 GPUs, but I'd assume that an application has to be programmed to take advantage of IFL specifically, correct?

Does anyone know if Adobe Premiere Pro treats 2x Pro Vega II GPUs with IFL as one GPU, similar to how it sees Crossfire on the Windows side? Or if it sees it as 2 separate GPUs, will it at least take advantage of IFL, or does it treat the 2 GPUs and just 2 separate GPUs connected via separate PCIe slots.

Any insight would be helpful in determining if this is a worthwhile upgrade.
