They might work in the rear if used instead of rear brakes. Rears do far less work anyway and brakes are heavy. Powerful electric motors can do a lot of regen, similarly assisting the front brakes.
I’ve had near 8 kilogram rear brake disks on a diesel wagon, not even a performance car that would require huge brakes, current car is 5. Calipers weigh a bunch too. Pads themselves are light, but still add to the whole setup.
