Sure, but in the case of "he finally did X" without context passed in, how does the llm determine if it would be expanded as "this was a very anticipated change" or if the author is frustrated at how long it took? If the nuanced meaning isn't there in the input context. obviously it can generate the longer message, but is it going to go look up what the sentence refers to and infer extra meaning automatically...?
