Unlike ML.EVALUATE, ML.ARIMA_EVALUATE is mostly about the model information, and can't be applied to new data. I didn't see that at first place.

That means it can't fit in model.score(X, y) story. I'm thinking of adding a .summary() method like https://www.sktime.net/en/latest/api_reference/auto_generated/sktime.forecasting.arima.AutoARIMA.html#sktime.forecasting.arima.AutoARIMA.summary. Lemme know what you think.
