Eve and all other 3rd party HomeKit-apps (Home.app is the only privileged one) are only clients using the HomeKit framework and its (public) capabilities. Rules are nothing Eve “runs”, Eve only is the user interface to set them up and hand them over to HomeKit. Rules are executed by a daemon process on iOS/tvOS that’s way outside of our reach. So yes, feature requests should be addressed to Apple. Nothing we can change:
Important: the Eve App cannot display any notifications, only the Apple Home app is authorized to do so.
