Yep, and the other thing is that something like 90% of DNS is "I need to update a A record or a CNAME or a AAAA (rare)" and then waiting for caches to expire.
But that's only like 10% of DNS's surface area, there's tons of other things it can do and rarely does, but if you have to make that stuff work you can get deep in the weeds fast.
