A video player seeking to the middle of a movie asks for a few megabytes. Under our old range caching, that one request could make Cloudflare pull 128 MiB from the origin and move it between data centers, sometimes after the viewer had already left. Range requests are how large files get delivered, and caching them naively easily leads to wasted network bandwidth and wasted disk operations when running a CDN at scale.
