Not sure what you're implying, but that was frankly the only solution if you wanted to create something that could be used by the majority of people with iOS devices. Proprietary "sugar" on top of standard protocols is almost the de facto answer for how Apple operates these days. Their efforts to get the extra stuff past standards bodies (so that everyone can use it) is at times hit or miss, but I'm increasingly convinced the overall approach is correct. Why Google can't do this on Android is an open question.
