No, $GENERATE is not why he, *I*, prefer to use NS over CNAME delegation.= I listed out multiple (2 ~ 3) manually as an example instead of using=20 $GENERATE purely to simplify the example.

The use of $GENERATE or not is independent of CNAME vs NS delegation. Besides, $GENERATE happily works with CNAME as well as it does NS records= =2E $GENERATE 1-4 $ CNAME $.bob.example.net. $GENERATE 5-8 $ NS ns1.example.com.
