Its also possible that this enables you to deploy all your assets prebuilt and optimized to a CDN? For Node apps running on services like fly.io this may be useful, since they're regionally distributed and their claim of running closest to the customers using it is at least partially true. This makes your deployed images (and therefore disk size needed) much smaller I agree that not having SRI as a requirement is a miss, however I see legitimate use cases here.
