That's assuming you trust the CPU vendor not to have their own interposer.

If you don't trust the CPU vendor in your machine you have bigger problems.

Given that the Intel ME and AMD PSP are both backdoors, we all have problems.

It’s only a backdoor if it’s undocumented.

Who has the keys to this backdoor? [for the curious]

At a minimum, Intel and AMD.

What kind of keys are they? In that same regard, Apple holds the keys to sign software for secure enclaves on iDevices and Macs, does that make them backdoored, since they can control execution on the firmware that protects everyone's authentication data and secrets?

Yes, Apple products are backdoored - not just through esoteric keys, but also because they're uploading your pictures to the mothership "to check they're not hild porn."

Citation needed.

Also, if virtually every software that is updateable by a vendor, then going by your argument, everything is a backdoor. Not a very useful term then.

Yes we do have those big problems.
