For sure you have a point in that for many years v3 didn't have the mechanism available and definitely was already largely usable, neither the decorations existed in the HP/SGI STL headers which people used to just drop-in in their systems circa ~1990s (thus completing large interesting C++ only projects). All in all, anyway, I think it's uncontroversial that the current *default* is Ok for the large majority of the users.
Can somebody provide me an example of a code that segfaults if "namespace std" is not default visible? I never had problems, neither with std nor with other libraries such as boost.Yes, that's my interpretation: users can use -fvisibility=hidden without getting segfaults because they've hidden parts of libstdc++ that must not be hidden.
