I assume that most MPI implementations will have the values be equal
just by how their f2c/c2f engines work (OMPI will). I was just
wondering if it's necessary to *mandate* that behavior.

Do apps really check handle equality? If so, I agree that anything
other than path A violates the law of least astonishment. I assumed
that not many apps do this, but I probably don't have a good basis for
reference.
