I believe this choice is because of MPI_STATUS_IGNORE - there is, in fact, both an IN value (don’t fill in the status) and an OUT value (place the status value here). We do note in the intro that the MPI IN and OUT do not exactly match Fortran, for these reasons.

3) The F08 bindings for all variants of the MPI_TEST, MPI_WAIT, and MPI_PROBE functions and the MPI_REQUEST_GET_STATUS function do not specify an INTENT for the status(es) parameter. We could fix this by including “INTENT(OUT)” in all cases (by choosing the correct Python setting).
