Anyone doing this would be opening themselves up to a world of liability, and probably a lot of customers who would say no. I know my work is dumping older ipads even though all our integrated software for meetings etc works fine just because it could be exploited and isn't receiving updates. Even the possibility of that isn't worth it to a lot of places. It doesn't matter if it's connected to a "closed" network, it still has radio(s) on.

And since so many places are so slow to upgrade, this is a known attack surface. Once you exploit that old-ass iOS, you have a compromised machine with radios sniffing inside your environment.
