[deleted] All of the features included in AOSP are included in GrapheneOS. Only features in proprietary Google components won't be included. Google app features will come through Google app updates.
In general, features included in the monthly Android mainline updates won't be included until Android 14 unless we backport them. These are open source as part of AOSP via a special set of mainline tags for each mainline module. It would be very complex and work intensive for us to build and ship each mainline module rather than the AOSP variants of the code which have the same security patches but don't get the new features except via yearly releases and to a lesser extent quarterly releases. Their migration to mainline modules hasn't been a good thing for us. We can eventually build all of these and ship them but we need far more developers and resources than we have today. Note that Android OEMs don't need to build these, since they use the Google Play mainline releases.
