For issues that annoy me, I just stop doing. Cars are not engineered for everyone's idiosyncrasies. It sounds like you are improperly shuting the car down and you're upset that it causes the car to function in a way you don't desire. Simple solution is to shut it down properly. Maybe that's what it's trying to make you do. Worry about the things you can change or control.
Here's something you can try. Most modern cars have staged shut offs and pre-activations of various ECUs. You likely worrying about a thing that isn't a thing. If you put the car in park, lock the doors, and walk away, most cars will shut down modules as it determines they are no longer needed, battery voltage is too low, or it feels you should not do. Shut the car down and walk away. Come back in 20 minutes and see if it's still active. I'm willing to bet, whatever you're complaining about has been dealt with automatically. Just like when you unlock a car, it triggers some modules in anticipation of being started.
Do the test, if it passes don't worry.
What are you actually expecting an owner community to give you? My advice is to operate the vehicle in accordance to the owner's manual. It is easier for you to program yourself to shut down properly than it is for you to program the interactions of the pcm, body electronics, and CAN bus gateway. What it is doing is not a defect. You're doing something outside of the recommendation of the manufacturer. What do you want to hear from us?
I have cars of different brands and I wish they all did things in an identical way most pleasing to me. They don't. Every time I sit down, I need to adjust to what I am in because they surely don't adjust to me. The VW manual can be shut down as I brake into my parking location. The Seltos likes to be shut down properly. The Audi will allow you to mishandle the shut down sequence as you do without leaving the ACC On. I still don't use your method, but do as they instruct me to do.
