Allen Pike:

The only thing we can do as developers to disavow support for these devices is require a version of iOS that won’t run on them. Unfortunately, Apple will surely continue support for the A5 in iOS 9. If they do so, we won’t have a mechanism to cut off support for these old iPads mini and iPods touch until iOS 10 has reached wide adoption, likely in early 2017.
