Offering wholesale cache dumps blows up every assumption about origin privacy and copyright. Suddenly you are one toggle away from someone else automatically harvesting and reselling your work with Cloudflare as the unwitting middle tier.

You could try to gate this behind access controls but at that point you have reinvented a clunky bespoke CDN API that no site owner asked for, plus a fresh legal mess. Static file caches work because they only ever respond to the original request, not because they claim to own or index your content.

It is a short path from "helpful pre-scraped JSON" to handing an entire site to an AI scraper-for-hire with zero friction. The incentives do not line up unless you think every domain on Cloudflare wants their content wholesale exported by default.
