No, not at all, PetscMPIInt it not even mentioned in the PetscDatatype
enumeration. The whole PetscDatatype this is kind of messy, and fixing
it should take some time, and this for sure will no make my h-index
explode, right?. For now, mapping MPI_INT -> PETSC_ENUM seems
workaround the issue just fine.
