As mentioned in one of the linked tweets, ME was possible to exploit through early-boot attacks before the HAP bit was even checked. So non-negligible things happen while it "boots".

While they are genuine vulernabilties, I wouldn't consider this a worse problem than being able to inject rootkits into other parts of the firmware which is also the case here.
And the understanding that we have is mostly limited to what is in flash memory, e.g. the ME's BootROM hasn't been dumped yet (as far as I am aware).
