We do need the abstraction since there are multiple C++ runtimes: c++, stdc++, MSVCPRT, stlport, etc.  Each one is slightly different.  Furthermore, libstdc++ supported the GNU and Solaris ABIs, libc++ only does itanium, MSVCPRT only does MSVC ABI.  So, we need to have some layer to differentiate between the various ABIs and just general C++ language support.
