There's a tendency to selectively block DNS traffic, which can be a
pain to debug.  Various network issues might only affect DNS recursor

I agree that on a clean network, a DNS recursor should be easy to set
up and maintain, but you often learn after the fact that your network
isn't so clean after all. :-(
