Probably not on a native Android device or even a Chromebook that ships a binder user space together with a kernel, but what about people using "anbox" or similar projects that allow you to run Android apps in a container?
It seems like a legitimate use case of the binder modules, but now there is a kernel Kconfig option that has to match a user space binary.
