At least on my iphone15 pro max, disabling AI also disables “Hey, Siri” commands. I had to go back and turn that on again.

Is this only on 18.3? On 18.2 I still use Siri and I don't have Apple Intelligence enabled and never plan to have it enabled.

It was post 18.2 upgrade. I was asked on a splash screen if I wanted AI and I “skipped for now”.
