[boost] range_value

I don't understand why there are so many implementations of the
range_value metafunction.  It seems to me that it should always be
defined to be:

  template <class R>
  struct range_value
    : boost::iterator_value<
          typename range_iterator<R>::type
      >::type
  {};

What am I missing?
