Actually, the JSON from what I understand is _quite_ closely tied to the
implementation. It is always "right".

The problem is that the JSON is *too* closely tied. There is no separate
implementation and ABI. The published "ABI" really is just an artifact
of the implementation. It changes as the implementation changes, and
that's not something the kernel can use in practice.

Really "ABI" to TDX means something very different from what it means to
the kernel.
