I think this is just semantic drift (though I am broadly sympathetic to “boo semantic drift”). I see this business use of the term as treating the “mind attuned to being immersed in” and “habitually, automatically reaches for” sub-meanings as the relevant ones, which is (almost as you say, but skew) not quite the same thing as “proficient when the ability is actively engaged”. The more you're trying to navigate a dynamic environment rather than hiring for tasks well-defined in advance, the more that distinction matters in practice.
