Many productions specifically want film grain. Directors and DPs have very concrete aesthetic intentions when they go for film grain, so you're likely to find lots of movies with film grain added in post when they were shot on almost noiseless digital cameras. (For instance, one might scan the grain from an old film stock and apply it to the digital footage later.) Netflix is only optimizing the pipeline here, trying not to mess with the artistic intent.
