CNAME Flattening server-side support

Hello,

let's discuss the possibility of implementing CNAME flattering server-side support. This is necessary for reduce and speed up DNS lookups via disabling ANAME support and block RFC compliant CNAME records at a root domains (CNAME cloaking in this context, i suppose🤨). More information here:

This is also already implemented in NextDNS. Correct me if I misunderstand anything🤔

Thank you!
Cheers🥳
