   I think this is expected behavior from pyarrow's perspective.  The extension type is registered here: https://github.com/pandas-dev/pandas/blob/1a254df2e7e5a100cad1af4a97eded5177ae7d3e/pandas/core/arrays/arrow/extension_types.py#LL57C33-L57C45
   
   So until that file is imported, Arrow doesn't recognize the extension type.  In other words, everything works if you change the start of the file:
   
   ```
   import pandas
   import pandas.core.arrays.arrow.extension_types
   import pyarrow.parquet
   ```
