The original idea of using the init function with preload_libraries was to eliminate library startup that was expensive and only needed once. Specifically in the case of libR (and presumably other libraries as well), the init time was much greater than the actual library load time. If it is removed from preload_libraries, then we'll pay that price for every backend startup, no?
