With the possibility of bypassing JTAG lock and reading firmware at least this one has practical uses compared to the ESP32 ""backdoor"". Thankfully still not quite exploitable in typical IoT use cases. Doing the same to a secure microprocessor (think smart cards, eSIM) on the other hand would be notable.
