pitrou opened a new issue, #39865: URL: https://github.com/apache/arrow/issues/39865
### Describe the bug, including details regarding any error messages, version, and platform. Originally found out by [Arrow Rust](https://github.com/apache/arrow-rs/issues/5354): when importing a Schema with an extension type, the extension type will keep its serialized extension metadata even if there is a corresponding registered extension. Instead, we should strip the corresponding metadata if the extension type is known. ### Component(s) C++ -- This is an automated message from the Apache Git Service.
