correct, it won't, unless someone works on enabling that. the same is also true for other parts of settings (like ringtone selection etc) -- this is unfortunate, but there's a saying appropriate for this: "there's no such thing as a free lunch" (https://en.wikipedia.org/wiki/There_ain't_no_such_thing_as_a_free_lunch) - you're getting the enablers, the remaining part is implementing the interface, if someone then wants to make this backend work elsewhere
