This is taken out after delivery at dealer and as it says, it’s to quickly disconnect and connect the battery.
This is long time gone!

All cars are delivered in transport mode so only with basic functions. The battery is connected, however all ECU are in transport mode.
You can start the car but no Radio for example.

Cars these days have 60, 70 or more ECU's ... Not a good idea doing a hard reset. It's like pulling the plug from you desktop PC or Router...lol
