The ability to split incoming data based on groups or geotags seems a fairly standard process-- --especially if you are trying to populate downstream applications with the ability to filter based on a single attribute. Since much of the data streams are outside of a user's control, these processors are invaluable to split up data into a way that is usable within the downstream apps (experience builder, dashboards, etc.) which are not well-designed to ingest multi-categorical data.
Since this tool is already Esri supported, let's add it into the standard installation and allow users to utilize it without the need to install the GeoEvent SDK.
