> English is quite forgiving as a language

it's a couple mutually-conflicting languages in a trenchcoat; forgiveness and flexibility are perhaps its defining properties.

To the broader issue: "polish" (in any language) is only valuable insofar as it makes the ideas clearer, attests to innate qualities of the author and/or the investment of their time, or carries its own aesthetic value. As LLMs make (a certain kind of polish) cheap to produce, the value of the middle category attenuates to nothing.
