It has not been widely agreed. I've explained at least 3 times now:
1. This change is not necessary at the moment because the default named.conf
already has a listen-on statement that lists only the loopback address.
2. What you're suggesting does not always work the way people think it
should, and therefore I want to wait before adding it until some other work
that I have in progress is complete.
