This issue was raised in the MPICH GitHub https://github.com/pmodels/mpich/issues/5413.

In MPI-3.1, we have C bindings for:

int MPI_Get_elements(const MPI_Status *status, MPI_Datatype datatype, int *count)
int MPI_Get_elements_x(const MPI_Status *status, MPI_Datatype datatype, MPI_Count *count)
int MPI_Status_set_elements(MPI_Status *status, MPI_Datatype datatype, int count)
int MPI_Status_set_elements_x(MPI_Status *status, MPI_Datatype datatype, MPI_Count count)

MPI-4.0 added:

int MPI_Get_elements_c(const MPI_Status *status, MPI_Datatype datatype, MPI_Count *count)

But no binding was added for an _c version of MPI_Status_set_elements. Was this intended?
