The point of an embargo is to allow vendors to coordinate patches. Since the exploit clock starts ticking when the first patch is released, releasing all patches at once means that everyone has some opportunity to patch before an exploit is in the wild. Releasing an exploit simultaneously with the patches gives people zero time to patch. In that sense it somewhat defeats the purpose of the embargo.
