That is an intriguing alternative.  I expect it will solve the use-case 
of adding, removing, and rearranging drives and adapters within a 
computer.  I also expect it will solve the use-case of moving the system 
device from one computer to another computer.  But, I expect it will 
fail to solve the use-case of moving a raw system image from one device 
to another device using dd(1), because the new device will have a 
different serial number.


But, two out of three is better than zero out of three with device nodes.
