IMHO we want to, so we have to at least make 98/11 code coexist in the same process image, which means mangling changes. That the code can't interoperate is understood. It will by the way not break unnoticed: interfaces using the problematic types would be mangled differently, and hence c++98 code would silently be resolved to a c++11 variant expecting a different layout.
