If so it may just mean that weak symbols are the wrong mechanism for
implementing some of these C++ features. If the ELF standards people
believe that the current ELF behavior is not mis-specified, we'd need a new
kind of weakness to support C++ well.

Good question. What's the right forum for asking that?
