I am puzzled by the perceived poor fit with RATS. To some extent, the spec just refactors the attest key triple from CoRIM. Depending on how the environment and constraints get defined, the end result may cut across a number of groups. However, this is not an uncommon occurrence. RATS consumes stuff from several other working groups, and so too could other groups consume this.

    Sure, I think that it fits poorly into all of SUIT, TEEP and RATS.

    Because of the "constrained" and CBOR basis of this, it does not really fit
    into LAMPS either.   One could punt to COSE maybe.
