It may be artificial, but when the _average_ user/low-level tech talks about
"ethernet", they mean whatever they can jack into the RJ45 in the wall or
perhaps a hub/switch in the closet. The vast majority of "ethernet jacks"
are of this limited nature.
This is relevant to the original question, which was whether one could just
plug a hub (or NIC) in to the CSU/DSU and expect to be able to "see" the
traffic on it. For the purpose of that discussion, I'm not sure even gigabit
ethernet would count.
There's always been a gap between what the average consumer/user had access to
at reasonable cost and what could technically be done within the scope of an
engineering standard. (This can be very frustrating when you're doing a home
project on a limited budget and you discover what those little extra features
within the standard actually cost to implement.)
