[boost] Re: utility::string_view and core::detail::string_view

Why not just let boost::string_view be an alias to std::string_view when you compile in C++17 mode?

Because then the compiled library and the user code need to either both be built in C++17 mode, or both be built in not-C++17 mode, and this creates problems if you're using a prebuilt Boost, e.g. one from apt-get.
