Wording matters when conveying information, ESL speakers should be working with fellow humans when publishing in a language they do not feel comfortable writing on their own.
Seems important to know. LLMs lie and mislead and change meaning and completely ignore my prompt regularly. If I'm just trying to get my work out the door and in the editing phase, I don't trust myself to catch errors introduced by and LLM in my own work.
There is a lack of awareness of the importance of the conveyed meaning in text, not just grammatical correctness. Involving people, not word machines, is the right thing to do when improving content for publication.
It should not be a word machine (which, I should point out, does not have a brain)
Solving this problem might just involve using some of the resources to support the output being correct in the required language. You can call that a "cost"
