Indeed, that’s why cbor-seq is a separate document (and a separate media type).

When updating CBOR, we just need to be careful not to rule out decoders that are fine to find additional data when done with the data item they were tasked to decode.  (Both for cbor-seq and for piggy-backing CBOR data in front of a binary blob in some other form.)
It took me a while to add that API to my CBOR implementation…
