Wouldn't it be easier to change the code to not pass a null pointer to
a std::string, than to change it to use a new, incompatible string
class?!

Or just use a helper function to construct your strings:

inline std::string safe_string(const char* s)
{ return s ? s : ""; }

There are many ways to solve this problem portably, but you seem
fixated on making the standard library change to accommodate broken
code.
