I had this happen to me about a year ago when this first rolled out in the US on Pixel Devices. My phone's power button was broken and kept toggling (still is). So, one day after this update, it ended up calling 911 on me and I had to explain no there's no problem, just my phone is garbage and called automatically. Did it a few times after that as well where I would have to scramble to cancel it.

I managed to make it to the menu described to turn off this feature. And gave up on fixing that device.

Really don't know what went on in the product owners minds to release this... There's plenty of people with finicky power buttons, children pressing things, general people pressing things hoping to make something work, accidental button presses, and so on...
