The whole thing? There aren't specific parts that are too SNP/TDX centric, the
entire tone and approach of the document is wrong. As I responded to Dave, I
would feel differently if the document were named tdx-and-snp-threat-model.rst,
but this patch proposes a generic confidential-computing.rst and presents the
SNP+TDX confidential VM use case as if it's the *only* confidential computing use
case.
