What's the surrounding use case you are thinking about?

Why does the standard not have std::iterator_const_cast? There is no standard way to convert type like std::deque<std::size_t>::const_iterator to std::deque<std::size_t>::iterator vice versa or  std::deque<std::size_t>::const_reverse_iterator to std::deque<std::size_t>:: reverse_iterator

 

std::iterator_static_cast can also solve the definition problem of contiguous_iterator, if an iterator T can std::iterator_static_cast to typename std::iterator_traits<T>::pointer and void*, then it is a contiguous_iterator.
