That works probably the best for me, effectively assigning aliases to
hardware mac.
I've only run into mac duplication a couple of times in my life thus far.

It solves the problem that Steve Litt brought up of chasing the same
piece of hardware around the USB buses and also allows interfacing with
equipment looking for another naming convention.

Of course when a network card or adapter is changed the table would
require editing.

Isn't the initial identification of network adapters and assignment
originally handled by the Kernel or is this another urban myth that I
have mistakenly hung on to?
