How does the output change? If changes may break someone's parser, it is worth mentioning that. Some people still have scripts that parse netstat output to automate their things.

To address this concern, I only emit nhop flags output with encoding styles like json and xml, AND only if the wide flag (-W) is specified.
It won't show up in normal output even with -W.
