The "problem" with them was that they apparently weren't consistent
across boots if you had multiples of the same "type" -- although I can't
remember that ever happenening, even on crazy frankenboxes that had 3
and 4 PCI NICs in them (barring moving things around, but these
"predictable names" change too).

I can't remember it ever happening either. The best "intel" I got on the actual linux shortcoming was that NIC numbering depended
on the order in which the NICs came up and responded at power-on. Although as you observe, I never actually saw a server come-up
out-of-order like that. Maybe PCI-mounted circuit boards are still deterministic devices today :-) If you work in a datacenter, you are 
configuring many servers at a time and machines are doing the work for you, so you tie the MAC address to the NIC and that's done at 
install time. If you were not doing that or other software you installed relied on fixed or slowly-changing interface names, there could
be problems.
