But it's handy when the recipient is less familiar. When I'm writing to my kid's school's principal about some issue, I can't really say, "Susan's lunch money got stolen. Please address it." There has to be more. And it can be hard knowing what that needs to be, especially for a non-native speaker. LLMs tend to take it too far in the other direction, but you can get it to tone it down, or just take the pieces that you like.
