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 🫠)
Does that actually bring up a menu, or just outright shut it down?
The two button shortcut has historically been for forcing an immediate shutdown in the event of like, a full system freeze. It’s the same as ripping the power cord from a running desktop PC, and isn’t the intended graceful shutdown that these devices are supposed to get.
Unless they’ve changed things, that’s been the standard since the first smart phones and PDAs.
For me it brings up this menu
