I see the CBOR list traffic in the archive (e.g.,
https://mailarchive.ietf.org/arch/msg/cbor/LyndIfQipxUfx0cu6nlOwi6ceOY) and
agree with the sentiment that the CWT spec should not inadvertently
over-specify the behavior of CBOR

The proposed new text is itself flawed, though, as it claims that strings
are an "other data type" with respect to strings.
