Coworker did that a few years back with a Hyundai, he got in at 6:30AM, we walked out to our vehicles, and he had the vehicle running with air conditioner on still at 5:30PM. 10 hours of idling, lol!

Push button start - will vehicle shut itself off if you forget to power off?

That is correct. From the owners manual:
Also, if you leave the vehicle with the key while the engine is running, you cannot move it out of park.

My Jetta will only push-button start if the key is in the vehicle or otherwise extremely close, and it will remain running even if you walk away with the key, but it will start beeping at you to let you know that the key is no longer in range. (It's not an annoying alarm, just a soft beep every 15 seconds or so with the display reading, "NO KEY.") I have only done this while it is in park though, like if I'm running into a gas station and leaving the family in the car while it's running to stay warm. I've never tried starting it, walking away with the key, and then seeing if it can be put in drive though.

Give and take.
Auto shut-off is great for mistakes but if one wants to remain inside an “idling” EV vehicle for extended periods of time (napping, camping, power outages, etc), then they suck. Big time.

That's true but personally I'd rather it cover my day to day mistake potential rather than help me out in those once in a while things. It sounds like if you have the keys in the car it'll stay on (camping, power outage) but I get what you're saying if a loved one is in the DMV for 3 hours its probably pretty irritating if they take the key.
For sure, I usually agree that just about everything should have a toggle. I'd be in favor of automatically re-enabling stuff such as auto turn-off if the user disabled it but it would be great to hit a button saying "leave it on" or whatever.
Usually these sorts of failsafes I find should be automatic because that is the point of a failsafe but I will always appreciate a toggle off even if temporary.

I find it hard that the vehicle will turn itself off. I would think there would be liability on Fords end for people sleeping or disabled that cant get out of the car and vehicle shuts down in summer. The vehicle would become a killer and most might not know the vehicle is designed that way.. Seems shady.
Okay let's try to reel this one back to reality, nanny features exist because people are fundamentally irresponsible. Aside from this, If I design a product with a particular set of functional features let's say for regulatory purposes or reliability improvements, then building in a toggle off switch is going to cost my bottom line eventually in most cases. Whether it was a lawsuit because someone disabled a safety feature and my warning doesn't legally release me from all culpability or if it was something as simple as me having to cover warranty repairs because I allowed my users to disable some smart feature.
To quickly address an aside, nobody ever got a fine because their car honked while parked period. If someone told me that happened I just don't believe them so let's keep the conversation in this reality. I know this is true because almost every car honks when you tap lock twice. Is it annoying? that's another argument but legally that is a farce.
To be clear I'm talking about the auto shut off after the car has been remote started or if an intelligent access user left the car on and exited, not about the auto-start/stop at redlights. Its possible that auto-start/stop is problematic in your particular area for some reason but I can't speak to that.
My career is with computers and the #1 rule is that you never trust anyone no matter how simple something is because they will find a way to screw it up and make it your fault. If I could avoid 200-300 phone calls by not letting users disable something I will and do. Yes it is annoying for those more responsible or in the know but usually things are that way for a good reason. In my professional life it is always for a good reason so I tend to give OEMs the benefit of the doubt unless I have a good reason to think otherwise. Also where would this end? Should users be able to easily modify the valve timing? hell no!
To break bread with you a little bit, I can't think of a reason auto-start/stop can't be turned off assuming there's no valid engineering reason. But crucially the discussion was about unattended auto-off who's sole purpose is for those forgetting about it thus having a temporary disable is the most appropriate remedy which to be fair is already in the vehicle.

TIP: On hybrids with an electronic transmission and shifter and a foot on the brake, one can use the START/STOP button to both A) turn the vehicle off and B) automatically place vehicle in Park (P) at the same time. Very cool Easter egg.
My c-max has an old school mechanical shifter so it can’t use this short cut properly.

This is just a guess, but I think the auto-start/stop plays an important role in gas mileage and emissions. If Ford uses that technology to achieve the ratings it gets from EPA it would be deceptive for Ford to then allow owners to permanently shut it off.
I think of it kind of like catalytic converters. They are part of the emissions control system and you can't legally remove them because it would change the emission profile of the vehicle.
