Also similarly, recursive resolver when talking to authoritative server might use multi-qtypes single query instead of 3 separate queries. It needs to cache that multi queries is supported. Similar to EDNS0 support indication.


I'm quite an opponent of complicating the DNS protocol in order to gain some optimizations. This all belongs to the '80s. Current DNS servers can easily handle 3x the normal load of _legitimate_ traffic like nothing. And if not, it's still cheaper to scale them than inventing and implementing multi-qtype.
