I'm probably missing something here, so I have to ask.
I said this was "trivial to fix" for the particular case of
MPI_ERRORS_RETURN. How should C++ bindings behave in case
MPI_ERRORS_RETURN is set? In other cases, I agree with you, fixing
this beast is not easy. However, you have a point about C++ bindings
being deprecated.
