But my point is that these days the user of the system will normally not be interacting with the device nodes and their names unless they are doing something relatively close to the hardware
If it's just your own system, then indeed, nobody cares. But think of managing hundreds or thousands of systems and you may see the value of being able to standardize device naming. The precise naming policy is not so interesting, but the fact that there is one that is consistent is really rather important.
