What the specification document says is irrelevant, since every implementation still supports the C++ bindings. They can be disabled explicitly in MPICH (and derivatives) via MPICH_SKIP_MPICXX and in OpenMPI with OMPI_SKIP_MPICXX.

It's a linking discussion, and you would only need to link libmpicxx.so (or whatever) if you actually used those bindings. We certainly don't do that and any other project that still uses them should be chastised. BTW, PETSc defines the above macros for simplicity and to avoid the unfortunate messes that used to plague the C++ implementations.
