Seems like an easy change to revert from the release notes. As far as the reasoning behind it, it is a performance optimization since most temporary files are small and short lived. That makes them an ideal candidate for being stored in memory and then paged out to disk when they are no longer being actively utilized to free up memory for other purposes.
