Is there a recommended way to add polars.DataFrame to _serializers and _deserializers?

[phi-friday]

I found that the pandas.DataFrame returned by Task can be serialized correctly because _serializers has added a serialization function to the pandas.DataFrame object.
And _serializers is lazily loading a canonicalized form of the submodule in airflow.serialization.serializers.

To make polars.DataFrame serializable, I can do the following

1. monkeypatch
2. define a custom provider (xcom backend)
3. add a serialization function to a private object _serializers

However, I don't think it's a good idea to do the above just to add a serialization function.

Is there a way to add a serialization function, or add a serialization submodule in airflow.serialization.serializers?
