And if they do, recursive service operators who haven't seen the message will (if they care) update their root hints. This seems to be exactly the right thing. I fail to see the concern here.

Are BIND's warning messages so opaque that someone who is looking at name server log messages can't figure out that the warning is talking about a root server IP address being changed?

The handwringing over this issue is a bit over the top.
