Is \v being mentioned in specifications really causing a problem? I've never seen someone mistakenly use a vertical tab in code where they could be using something better. Maybe it's useless, but I wouldn't say it's harmful. This is a pretty overzealous rant over nothing: it's almost as useless as the vertical tab.
