There are many open source contacts, calendar, etc. apps. Google is so caught up maintaining its own apps that talk to its services that I don't know why anybody would want Google's own half-assed open source implementations. Even if you wanted Google to maintain open source versions of those apps, why would you want them to be updated at the cadence that AOSP is and have them be developed in AOSP's non-collaborative manner?
