Unity and Admob using latest Play Services Plugin

The latest AdMob plugin for unity updates are over 6 months old, and google seems to be saying it is now integrated in the play services plugin, so how do I stop using the admob plugin and start using just the play services plugin? There doesn't seem to be anything like "using GooglePlayGames.Admob;" or similar, so how in the world do I use types like "BannerView" and "AdRequest", which the admob plugin relied on? Am I missing something here, or has google forgotten about ol' unity?
