It applies to mostly everything, except perhaps pure implementation details 
of DLLs.

And, if we're talking about string_view in particular, it's often used in 
interfaces as a function parameter so it'd be pretty much guaranteed to blow 
up unless boost::string_view and std::string_view happen to share the same 
layout.
