That's like a huge "duh, why didn't they do that" sort of thing. Wow. Theoretically, they could probably make all of the free space in the washer part of a giant tupperware style container and allow filling of different compartments to precisely balance the machine.

Traditionally we used a system that was not prone to this kind of failure, but now that the cycle is computer controlled and we have cheap accelerometers we can use a more complicated but lighter alternative safely.
