For scripts that are always delivered through a single URL, no standard
change is needed in order to make this optimization happen. As Boris

Unfortunately, for framework caching, using only URLs for caching purposes
have proven to be insufficient, resulting in very little code reuse across
sites, because of multiple CDNS and versioning [2]
