Independently powered wheels don’t have the proactive traction-management of mechanical lockers and thus are limited to reactive traction-management.

This just isn’t very accurate as far as I can tell. The physical strain characteristics of a steel transfer case and drivetrain respond to forces in approximately 1ms (the speed of sound in steel over a 14 ft linkage). That’s the same speed resolution as a good quality computer controlled system. They’re exactly as “reactive”.

There’s nothing “delayed” about a good computer drive system, even compared to mechanical linkages. A well programmed computer system would be superior in every possible way. And you could just program it to only ever allow wheels to spin at exactly the same speed, exactly duplicating a mechanical linkage, with zero disadvantages (and much less complexity).
