You really need to file a bug report about this.
<https://developer.apple.com/bug-reporting/>
By way of context, I just updated two of my victim devices (an iPad mini 2 and an iPhone 5C) to iOS 9.2.1 and CNCopySupportedInterfaces is working just fine on both of them. I tested it with a simple test app run from Xcode (code below). Due to the nature of my job I always use production devices, iOS builds, OS X builds and Xcode builds; there's no Apple-specific magic going on here.
So clearly this is not a universal problem but something more nuanced than that.
Please post your bug number, just for the record.
Share and Enjoy
