What is the user facing impact of this?

There is no impact on the user side. The Earth Engine API currently does not provide a complete list of available filters and reducers. As a result, we need to hard-code these lists in order to present them as selectable options to users. We recommend that the Earth Engine Python API development team add a method to retrieve the full list of filters and reducers.
