Dictionaries have been trying to retard linguistic progress since the first edition of one tried to nail down every meaning of a term.

Webster provided a common reference for the American dialect: he helped unify the dialect. Or partly unify: "Redd up your room annat" isn't comprehensible in most American cities, but is still proper English in Pittsburgh. (Of course, nowadays better dictionaries probably list "redd" and "annat", even if they're not used across all of the US.)
That being said, I have seen people weaponize dictionary definitions if that’s what you were referring to.
