I’ve confirmed through the source code and #5070 that the `IntoPyObject` derive macro supports the same field attributes as `FromPyObject`. However, the [doc](https://pyo3.rs/v0.27.2/conversions/traits.html) only mentions these under the `FromPyObject` section, making it look like `IntoPyObject` is not customizable. As I'm still new to PyO3, I'd prefer if someone more experienced handled the documentation update to ensure all technical details are correct.
