It has been rather nifty that if I walk up to a random machine with exactly one NIC (that I've been asked to examine/fix), I _know_ that there will be eth0 and only that. OTOH, maybe it's a good idea to make admins do "ip link sh" and "ip addr sh" every time they examine a new computer -- it goes a long way to root out wrong assumptions in that field.
