The question I have is if CBOR and COSE are simply content-transfer-encodings and not content-type.  This gets into a nebulous area when discussing reasoning over volumes of data.

If all the content is signed it would show as homogenous data application/cose and thus any filtering would require tunnelling into the payload which could be expensive.

(I was writing an ID for this, then realized that application/cwt was
already a thing, and that all we needed was a suffix, which is Expert Review)
