This violates RFC 9156 Section 3, step (3) and it is not necessary. It also breaks some (weird) authoritative DNS setups, especially when CNAMEs are involved. Also there is really no privacy leak with query type. Closes #5661 Merge branch '5661-dont-minimize-when-QNAME-matches-original-QNAME' into 'main' See merge request isc-projects/bind9!11293 --- 15494053b122ae52039e8a2772041cbabc7d05a3
