Everyone focuses on the letter and how it's written. Nobody tells the Dear Author to assume good faith and best intention and Optional Details Are Optional.
I think it's possible for a recip to put down a letter that specifies the things they like while the author also assumes that the framework was created with the best intention to make it easier for the author to write something to the recip's tastes.
I think I misunderstood your original post. You're saying something like, writing a Yuletide letter from the point of view of "I want this/don't want that" versus writing a yuletide letter worded as "if you want help creating a story for me."
