I was struck by the "Magnitude: High | Applicability: High" bit. Who writes like this? More importantly, who reads like this? The V4 doc (which I have yet to read, but I did a text search) has 64 occurences of this sort of phrasing; not actually all that many, given that there's 293 pages, but enough to be interesting. I wonder if this extra stuff is there to make LLMs pay particular attention.

Intel's software optimization guides have similar annotations on many of their guidelines, and have done since long before LLMs were a thing. As a reader it's useful to know how impactful a given recommendation is and how generally applicable it is without having to read the more detailed explanations.
