My theory, based on what I would see with non-thinking models, is that as soon as you start detailing something too much (ie: not just "speak in the style of X" but more like "speak in the style of X with [a list of adjectives detailing the style of X]" they would loose creativity, would not fit the style very well anymore etc. I don't know how things have evolved with new training techniques etc. but I suspected that overthinking their tasks by detailing too much what they have to do can lower quality in some models for creative tasks.
