You totally missed his point. He's not saying the experience should present to the user as anything but what it does now - but behind the scenes there isn't any reason for the universal binary to exist. The phone or tablet should just download the binary it needs.
I talked about backup and multi distribution of the same app to different devices in one batch. Isn't that enough "behind the scenes" related? I understand he wants the better of both worlds, a light download for each device and still full compatibility with each. But just thinking about it 30 sec and there are plenty of cases where the magic breaks and you find yourself in a corner with only one version when you need the other. You can say "throw the edge cases away", but it' unrealistic to think that you can keep the same usability in everycases while heavily cutting on the data you transmit to your users. Let's be honest about the compromises.

Name a single one an end-user would encounter. They wouldn't.
