I consider it wrong

 * to include <iostream> when the standard streams do not get used
 * to include <iostream> as a shortcut for including <istream> and <ostream>

The latter isn't guaranteed to work, IIUC, since <iostream> could be
written as #include <iosfwd> \n extern std::ostream cout; etc. That way,
the free operator<<() functions from <ostream> do not get included and
some output will start to look funny.
