De-duplication can prevent multiple copies on disk, but we're out of luck on reducing network costs. Shared caches must make sense within this value system. That is unlikely given the need for SRI annotations or the unbecoming practice of speeding up high-traffic sites, but not others. That's how much wire size matters.
