Actually, the current `mpi_f08` binding only supplies the `C_PTR` interface. We'll need a `MPIR_F08_C_PTR_2_AINT` C routine to provide the AINT interface. This is doable.
PR #5784 will fix for the `mpi_f08` module. However, this ticket was referring to the `mpi` module. That will wait after #5685.

@raffenet So for this issue, all we needed is a non-standard hint so that we skip intercomm connect/accept?
