In enterprise and file geodatabases, the Shape.STArea() and Shape.STLength() fields are automatically calculated after modifications. But for a lot of local government folks in the US working with land-related information, "acres" is a more important geometric measure than "square feet". But to keep this user-created field current after modifications, it always has to be recalculated manually or programmatically. Forgetting to recalculate can lead to erroneous assessment results. It would be nice if the automated geometry update of the Shape.STArea() field could be applied to other geometry fields in the geodatabase as well.
