AlenkaF opened a new issue, #39094: URL: https://github.com/apache/arrow/issues/39094
### Describe the enhancement requested Currently `__reduce__` method is defined on the `ExtensionType` class so that each subclass can be pickled and doesn't need a separate `__reduce__` method (see https://github.com/apache/arrow/pull/36170). But this can be cleaned up. Instead of defining `__reduce__` for `ExtensionType` we can define `__reduce__` on `BaseExtensionType` and make use of the C++-level (de)serialization. See https://github.com/apache/arrow/pull/35933#issuecomment-1841014923. ### Component(s) Python -- This is an automated message from the Apache Git Service.
