Besides commercial studio shooting and classroom situations, is there
any real need for tethering?

Besides the 1.0 crop factor sensor, is there anything _fundamentally_
different between FF cameras and comparable APS-C cameras? We should
really think long and hard about how some other manufacturer's FF body
would enable us to improve our photography or enable us to shoot
subjects that are impossible to shoot now.

I'm not saying there aren't good uses for a FF, but many of us are
evaluating the leap from, say a K-5 to a Nikon 800E. Feature-wise
that's really a jump from a semi-pro to a pro level camera. The
features you gain there aren't attributes of FF per se, but rather
they are pro level features.
