I'd love to see it. This is definitely software and not the flywheel. It's in many, many modern cars. Lots of older cars with dual mass flywheels have zero rev hang. The E46 M3 and Z4M have S54 engines with DMF and have zero rev hang. The revs actually drop too quickly to shift smoothly at times because the gearbox is so clunky.
