No, no, no, f.e. boost::mp11, or boost::beast are to be compiled with C++11 and should therefor use std C++11 libraries instead of their equivalent boost version...

That's what they do; except Beast uses Boost.System because ASIO uses it, and it uses Boost.Optional and boost::string_view because std::optional and std::string_view are C++17, and so on. It's not like we go out of our way to avoid using the available standard facilities.
