> Why would DNS have "optimized, localized results"?

Any content that is CDN-based (which is most content) dynamically responds to DNS queries based on network and geographic location - to support CDN localization. In this way, Akamai for example knows the end user is in Boston on a Comcast network and will send the recursive DNS server a dynamic response that points to a directly-connected local-to-Boston content server.

Any serious CDN is doing that with anycast, not with geodns which has tons of drawbacks.

That's not the case - many use hybrid approaches, and GeoDNS is still used heavily in the industry. Anycast sucks too.

You're right. This is really cool tech. https://www.cloudflare.com/learning/cdn/glossary/anycast-net...
