"If the origin response does not include a Vary header, Cloudflare caches the response normally"[1]

"If one response omits it, Cloudflare could cache that response without the variance needed to keep it isolated."[2]

Will that non-Vary cache object front-run any Vary-segmented cache objects?

If so, probably worth adding a snippet rule to ensure every response has a Vary header?
