I think folks are trying to break apple's stranglehold / monopoly so that other app stores can be offered on iOS. This should help address these types of issues so more devs can get onto iOS more easily without having to meet Apple's level of requirements.

Well if an app developer does not ensure that their code works on a device that only has an IPv6 address they will be in for a big surprise: lots of mobile telcos only give out IPv6 addresses.

Connecting to the IPv4 world is done via CG-NAT with the first few hops being IPv6-only.

Here's a guy from T-Mobile presenting on it:

Require IPv6 support (or fail upload to store) is a good thing.

If your server is ipv4 only that's okay because it's still reachable via DNS64/NAT64. I know because I've uploaded apps like that recently.
