Becase Ethernet addresses are only locally significant, are not manually
assigned in the vast majority of cases, and changing a MAC by replacing a NIC
has no bearing on the configuration of a { server | router ACL | etc }.
Layer 3 addressing is globally significant, and the case we're discussing is
addresses which are human-assigned rather than automatically configured.
Link-local autoconfiguration in IPv6 works like a champ, and behaves pretty
much the way I would want it to. Global addressing approaches, on the other
hand, are highly optimized in directions which make them less flexible or have
surprising consequences (hence this thread).
