Appreciate the list of Navi cards "supported".
It would be helpful to the readers and members here to mention a "caveat".
That caveat being that the "AMDRadeon6000kext and supporting kexts to allow support for the new Navi cards" for GUI acceleration of the macOS User interface and not necessarily the acceleration of H.264/HEVC video encoding/decoding in specific macOS Apps (e.g. Quicktime, FCPX, etc). Unless, you can list the Apps that will work with these "supported" Navi cards.
That is, "support" does not necessarily mean support for encode/decode of those codecs via the Navi cards.
In other words, you would not want to inadvertantly mislead any users into assuming that if they bought a new navi card (because it is listed here), then it will "just" work with their video editing apps. It may or it may not.
I suggest a caution should be added to you original post.
