Having seen the PCI eth device flips before between update releases of EL4, to give one example, it's really nice to be able to really know what device you've plugged a particular cable into, and know it in an unequivocal, and unchanging way.
Yes, good comparison. Imagine if you had to guess which router
interface or managed switch port configuration/name is connected to
which wire. That's exactly the situation you have with a multi-nic
linux box - which may have an equally complex network setup. For things
that don't need the bandwidth of multiple interfaces I've found it
easier to use a single VLAN trunk connection and split the subnets out
with vlan interfaces.
