   @jorisvandenbossche Looking at the docstrings for the `types_mapper` I think item 1) from your list should test if `None` is added in the mapping function, then the default conversion is used. For example: `types_mapper = {pa.int8(): None}.get`. 
   
   > The function receives a pyarrow DataType and is expected to return a pandas ExtensionDtype or None if the default conversion should be used for that type.
   
   Is that what you meant?
