Some choice at least would draw the attention. Though it is hard to say whether this would be seen as nuisance. For a fresh install I would assume the installer sets things up. At least after that there is enough information in the created file to alert anyone touching it. Must admit I don't know whether there always was one which I ignored out of habit. For myself it is not that bad anyway as I only have a limited number of personal use machines. Just trying to anticipate what happens on a larger scale role out.
Would it be an option to do nothing (not touch resolv.conf) if there is neither an active interface with dhcp nor dns-server lines in /etc/network/interfaces? Though that surely has the drawback of not really giving a hint about the newer way of defining things.
