>increases the trust boundary of a TEE (for instance, with unverifiable trust dependencies)
Is there an example of this in RATS drafts / RFCs?

Thanks Thomas. I understand, which is why I stopped participating actively. In the meantime, any standardized CC interface or protocol that implicitly increases the trust boundary of a TEE (for instance, with unverifiable trust dependencies) inherently degrades the CC business value proposition from the start.

Thanks,
Manu

While CC is obviously a very relevant use case, RATS is not chartered
for standardising confidential computing.
RATS is chartered to ensure that use cases with a stake in remote
attestation (including confidential computing) have standardised
interfaces on which to build their added value.

cheers!
