What I suggested has the ability for Boost developers or anyone else
to #define BOOST_NO_GCC_SYSTEM_HEADER to disable the use of #pragma
GCC system_header within Boost, if we adopt it. Would you agree that
this is better than just using #pragma GCC system_header without the
ability to disable it? :)
