You can test your application, game, website without a physical phone?
Can do that with the simulator too
I have had instances where the app runs fine on the simulator but crashes on the device. This might solve that.
Running on ported userspace components, with a shim, isn't the same as running on the OS in itself.
That really matters, sometimes.
But not the vast majority of the time.

Can you give some examples of where it matters? I'm genuinely curious.
Last I checked, VPN network extensions wouldn't run in the simulator.
Is the simulator faster than this? I would suspect so.
