There are the AMX machine learning on-die accelerators. I assume there's some new instructions to talk to those.

You don't need special instructions to talk to peripheral devices. The ISA supports that from the get go. As a licensee, you can't add instructions to the ISA, only ARM can do that. That's what they do, they're the custodians of the ARM architecture.
They are probably just peripherals, like the GPU. I'd be very surprised if Apple strayed from the ARMv8 specification and added new instructions for those accelerators.
That whole thread is just speculation, same as what we are doing here.
