As a cyclist, what do I want to be notified about that is up ahead? I can't think of anything except maybe impassable traffic, but I don't encounter that often. In the city, I know there is always a cyclist ahead as long as I'm breathing. Really, we are very common here. In the country where we spend weekends, if I learned there is a cyclist ahead, what am I supposed to do, wave? I do, so how will the warning help me?
