You could update the protocol version if and when a protocol weakness is discovered and then stop talking the previous protocol version after a transition period.
No need to continuously expire apps in the absence of a protocol breach.
What if there's a vulnerability in the app itself?
I have no idea if that's what they're concerned about - they may just be being arseholes in this case - but from the outside it seems like a legit reason to build in the capability for app expiration.
