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.
