MacRumors reports Restoring a Bricked iMac Pro Requires a Second Mac and Configurator 2:
"If an iMac Pro becomes unresponsive and requires restoring, like if there's a power failure during a software update, there are a special set of instructions iMac Pro users must follow, which require a secondary Mac."
As outlined in an Apple Configurator 2 support page, an iMac Pro restore requires a second Mac running macOS High Sierra with internet access and Apple Configurator 2.6 or later installed.
[...] This restore process is similar to what must be done for an iPhone or iPad that is unresponsive, and it is necessary due to the extra security afforded by the Apple-designed T2 chip ... [which] integrates the system management controller, image signal processor for the camera, audio controller, SSD controller, a Secure Enclave, and a hardware encryption engine.

Bricked means "can't be fixed without hardware modification", not "the OS needs to be reinstalled from external media".
(Yes, I'm going to keep tilting at that windmill.)

yeah I thought bricked meant no cursor.
Not even "insert system disk or other boot media"
Seems like recovery is possible by having a local storage device with a working image. sort of like having a system disk.
too bad they dont want people controlling those aspects of their hardware unless you happen to own another licensed computer.
don't they let you make backups or does that also have to go into some clowd?
