So what's the idea with that? Build it beefy enough to withstand most prangs, or is it some sort of stupid self-destruct lever?

Derailleur hangers are about saving the frame in a prang mostly. Now it bolts straight to the bike by the rear axle so the frame isn't at risk of any bending. But yeah they're pretty beefy. There were several videos of people jumping up and down on the derailleur

The mech attaches either side of the frame. The top half of the mech with all the electronics and motors is really robust. If the cages get bent they are easily replaced.
The mechs are a piece of piss to set up as there are not even limit stops to set up. You will find loads of videos on MTB YouTube channels about them.
In addition the system shifts better under load than soft pedalling, so works amazingly well with e bikes where you are (if the motor is on) having your power supplemented.

I think technically it replaces the universal derailleur hanger and clamps the rear mech directly to the frame.
SRAM t-type groupset, so only compatible with frames built with UDH compatible dropouts.
