I think it is healthy to cover all maps providers anyway. I had a rude awakening too a while back when I wanted to do a native Android hack on Google Glass using maps, but there is none of the usual MapActivity, etc. available. So Open Street Map was the way to go. Google Maps sometimes just isn't the solution, so it is good to know many.
