I think that you made a good point.
But for RedHat perspective, a good release is “one that works”, not “one that comprehends everything”. Therefore the steps listed by @capote could help someone understand if his hardware could work on more recent kernel, even hardware updates are still not backported by developers on supported RedHad kernel.
I am thinking, for instance, on Ryzen-Based embedded APU by AMD, far more interesting than G-Series. Or Gemini-Trail.
I know, most hardware still not on market, but in few months some things will arrive… Without Spectre and Meltdown companions.
