They've effectively created their own TPM chips that displace a lot of 
Intel functionality, that they can register their hardware devices with.

For example, you can swap the cameras on two iPhone 12 devices and you 
will see random glitchiness... swap them back, work fine.  This is 
because they intentionally put buggy behavior not just with "valid" 
components, but those registered directly on the device.

True, but modern virtualization hooks in the processors helps a bit if 
you're emulating for the same architecture... that said, Mac switching 
to ARM won't really help x86 software in emulation much.
