I know this is just anecdotal but this is what helped me sleep at night. There was an collision about four years ago where a loaded dump truck going ~70km/hr (so ~43mph), basically ran over a small car from behind that was stopped to turn left. There was no evidence he even touched the brakes. The car was unrecognizable, driver died instantly but the kid in the back in a RF AOE was ok once they were able to get him out (well he had broken legs and black eyes from hitting the seat back but all things considered he was good). Had his seat been tethered he would have had considerable forces on his neck (obviously can't say how that would have turned out or if it would have been worse/better than broken legs and black eyes).
** note - see post below with corrected info about the injuries ** Sorry for posting inaccurate details.
Personally I kind of like the idea of it acting like a spine board that moves with the kid. I can see how it would be advantageous to tether in a side collision and if I had actual anchor points to RF tether too I might consider it especially for my now big kids but I'm personally not comfortable using my front seats as untested anchors so all of my RF seats aren't tethered.
Anyways, nothing official but maybe it will cause some thought.
