I thought we already agreed to do this. :) With Apple announcing that iOS 11 will no longer support 32-bit applications, let alone CPUs, there's very little value in us supporting it. 80-90% of iOS devices will likely be on iOS 11 in the first week or month of its release, and of the percentage that aren't, only a minority will be the 32-bit iPhone 5.

We probably even support too many iOS versions as it is. Apple's official recommendation is that your deployment target should be "major version one below current, maximum minor version" - i.e. when iOS 11 is out, your deployment target should be 10.3.
