Who would need to press the power button to actually turn off or restart the device, right?
The setting to change this is also pretty much buried under Settings -> Special Features -> Gestures.
(Yes, I have no idea why the Assistant is in German when the phone is set to English either 🫠)
That was a feature two years ago I thought, long press for the “assistant”. I switched to grapheneos as soon as I got a pixel so I don’t follow Google’s actual releases
