Their "solution" just seems to be a way to introduce a trusted stub server in the middle of a DNS lookup request that can anonymize your queries. That's identical to just trusting your initial recursive resolver to provide that service and using DNS-over-TLS. That's what most privacy focused VPN providers, Cloudflare, etc include. So why would we break existing DNS implementation to support ODNS?
