Admob v2 with iOS

Hello,

Quick (odd) issue/non-issue I’ve noticed when creating builds.  I was under the impression that, when building for iOS with Admob, this line in build.settings was still necessary in the plugins section:

[“plugin.google.play.services”] = { publisherId = “com.coronalabs”},

However, we’ve also created builds with this line commented out, yet Admob ads worked just fine.  

Is this line optional, then, in iOS builds?  Or is this some bizarre oddity?
