If you are hiding CSS/JS from search engines, you probably have something to hide.
No. Hiding JS and CSS is about bandwidth and speeding up the search engine crawl and most importantly assuring that the site visitor's experience is not impaired due to crawler activity. As web publishers we want the search engines to focus on the content and then get out- without disturbing our site visitor's experience.
It is also an ethical problem where Google is overstepping a boundary line.
