Yes, that is a very interesting thread, and I don't even have a ZF transmission in my X5.

From that:
"Why was his invention so important? Well, in ZF’s case - compared with the 5-speed 5HP24 unit that it replaced - the 6HP26 had 29% fewer parts (down from 666 to 470), was 44mm shorter (reduced from 697mm to 653mm) and weighed 12% less, despite its higher torque capacity and increased ratio spread. Most of the world’s OEMs switched to 6-speed transmissions as a result."

I hope the guy made a lot of $$ from that great invention.
