Differentiate regression and forecasting of time series

Currently, regression models (i,e. LinearRegressor) and forecasting models (I,e, ARIMARegressor) are categorized within regressor estimators,

I think the time series forecasting model should have its own estimator category because the forecasting models should not be used interchangeably with time series and normal data. This is why the sktime also differentiates between forecasting and regression models.
