Share resolver cache accross PoP's (Think CF Argo but with DNS resolvers)

Are there any plans to share the DNS cache of a PoP with other PoP’s in the same region? (Similar concept to Cloudflare Argo, but for the DNS resolvers)

As In the case a DNS record is not cached in the local PoP it would likely be faster to do a lookup in the cache of another Cloudflare PoP, instead of going to a remote authoritative DNS server.

This should probably be implemented like a race condition: query both the authoritative DNS and the nearest Cloudflare PoP’s. (Or take it a step further and also add third party resolvers in the mix, like Google DNS and Quad 9)
