Yeah, the switch case I removed makes it fall back to the default, which
uses the custom serializer. This will fall back to the function
https://github.com/apache/arrow/blob/a04301833f585a66fa371394c9ee33a4a59c2ed8/python/pyarrow/serialization.py#L81
which converts the array to a list upon serialization and back upon
deserialization.
