What you described is exactly what WeChat is able to do and doing well. It has a half billion users (including every Chinese I know) yet comes with no social baggage. If you don't like the social features (called Moments) you can turn it off, or simply use WeChat as an IM and hardly notice the existence of all the other features (there are not many anyway)

So your enriched version of address book does exist, but only in China, and it is one of the few things I miss so much when living outside China.
