> I skimmed and had some wishful thinking that they just made a cheap off the shelf chip do the job of a TPM2 by slamming in an existing TPM2 implementation.

Is there any evidence that it wouldn't be possible - does Windows have a list of approved EK certificate authorities it expects?

The only reason I could think for this would be DRM, but I wouldn't expect this to be a requirement merely to install the OS (the un-approved TPM would still be good for any non-DRM uses, and would be useful in VMs where the TPM is already emulated by the hypervisor).
