There's a big difference between style transfer in art vs. literature or code. In art, it's ok to get close enough, laymen will forgive a lot of noise. A lossy painting is still a painting.

With great literature, every word is carefully chosen. You can't take something like Franz Kafka and randomly fuzz it, you'll destroy hidden features which differentiate it from the mediocre.

With code it's even harder. There's almost zero room for noise, a stray period throws it completely off.
