Android Marshmallow permissions model

My phone just offered to upgrade to Android 6.0 Marshmallow.

This looks like a good thing:

"With the new app permissions model, you pick and choose which
permissions to grant apps at the time of use."

But this looks like a big missed opportunity:

"To determine if your app has been granted a permission, call the new
checkSelfPermission() method."

Are there good examples of APIs and user interfaces for this stuff?
Did CapDesk get it right?
