   Indeed it seems the `safe` keyword is ignored _if_ we are using the python_to_arrow.cc code path (in contrast to the numpy_to_arrow.cc code path). This is similar as a recent issue that was opened with a variant on this (using list arrays): https://issues.apache.org/jira/browse/ARROW-16491
   
   A simplified example (even without using a nested type):
   
   ```
   # input is a python list -> safe keyword doesn't work
   >>> pa.array([3046682132], pa.int32(), safe=False)
   ...
   ArrowInvalid: Value 3046682132 too large to fit in C integer type
   
   # input is a numpy array -> safe=False has effect
   >>> pa.array(np.array([3046682132]), pa.int32(), safe=False)
   <pyarrow.lib.Int32Array object at 0x7f40e939f040>
   [
     -1248285164
   ]
   ```
   
   So going to close this, and add the example at https://issues.apache.org/jira/browse/ARROW-16491
