Comment 2 for bug 936976

They do differ, because as you said GetAll() is automatically done by gdbus (even now, so there'd be fewer context switches!), so we get rid of the time where a lens proxy is half-initialized ie connected but not knowing if it should search in home view, is visible, etc.

Moreover we don't need to break the wire protocol, the InfoRequest method can stay, but we won't use it.
