You can already do this with apps supporting chaining. They can support passing all the traffic through another app already.
Lock to 1 WiFi: I do not need Graphene to search around for additional WiFi options if my primary WiFi is not available. Even with MAC randomization, it's more data than I need to be emitting.
Scanning for Wi-Fi access points doesn't leak data as long as you don't have any saved hidden SSID APs.
