The problem is that explicitly because network devices have never been
enumerable in /dev before, every single utility does it themeselves.
Mostly by trawling /sysfs these days, but still... attempting to move
to an alternate naming scheme library could/would break everything that
only knows how to enumerate the kernel devices.
