OpenGL Template has view controller now

[strider2k]

I guess I never noticed it until now but the when creating a new project in XCode, the default OpenGL Template has a UIViewController in it now whereas the older one did not. Was there a reason for the switch? Are Apple employees trying to encourage UIViewControllers instead of us creating a class managing our own view stack? The only pro I can really see is the shouldRotate... didRotate... methods which handles orientation.

Edit:
I also remember seeing an Apple example with GL1 and GL2 renderer classes for OpenGL ES 1.1 and 2.0 differentiation. This newest example seems to deal only with shaders.

I thought the addition of a view controller in the OpenGL template was to make it easier to work with other API's that require a view controller -- like iAds and Game Center, perhaps -- though I'm not 100% sure, as I haven't used those API's and don't know what they actually require.
