You could A/B test different app behaviour with the same binary by branching on some pseudorandom (quasi-) constant like IMEI or phone number.

Sure. But once you know that everyone has the same binary, you can reverse engineer the binary you know everyone has.

The nice thing is that you can reverse engineer it and sniff traffic to find out what the A/B tests are and what they do.
