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.
