Right and my recollection was from moving our self hosted authoritative name servers to new ip addresses and dealing with unclear/delayed updates to those glue records. Of course this was 20yrs ago and the UI for making changes was much less slick and real-time than it is today. Got through it just fine without DNS outages but we did have to be methodical and check dig output carefully along the way.

You could stills misconfigure them, but it's unlike it will be due to forgotten/missing records. Which I think is the most common issue, because people don't understand enough how DNS works to know those are needed
