By "backwards compatibility" I mean the ability to use the new LAN from
a laptop that didn't have an Ethernet connection built in, and didn't
have an optional [proprietary] internal Ethernet card available either.
Later on, of course, you would get PCMCIA cards and USB dongles rather
than Centronics-port dongles. But the market for these remained
dominated by the Ethernet standard, rather than others.

That tale of woe doesn't really sound like it's the fault of backwards
compatibility. Didn't the operational status of the LAX immigration
department fall to zero for almost a whole day, once; as a result of a
rogue network card crashing the LAN?
