C++23 could get
http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2021/p1989r2.pdf
which means that std::string_view can be implicitly constructed from
another range (e.g. boost::string_view) without boost::string_view
needing a conversion operator. Similarly if boost::string_view adds
that range constructor, it could be implicitly constructed from a
range like std::string_view.
