> Asking for interoperable batteries between vehicle brands is like asking for interoperable engines between vehicle brands, it's ridiculous

No, it is like asking batteries for radios follow the norm (so that they can be swapped), or petrol to be the same for all cars, with the same pouring mechanism (a round hole), or USB connectors to be the same between devices.

Swappable batteries preclude the large weight savings of a structural battery that is an integral part of the car's chassis.
