Proposed resolution:

This resolution is relative to N4687.

Edit [iterator.container] as indicated:

-1- In addition to being available via inclusion of the <iterator> header, the function templates in 27.8 are available when any of the following headers are included: <array>, <deque>, <forward_list>, <list>, <map>, <regex>, <set>, <string>, <string_view>, <unordered_map>, <unordered_set>, and <vector>.

basic_string_view has size(), empty(), and data() members, but including <string_view> isn't guaranteed to give you access to the corresponding free function templates. This seems surprising.
