I wish I could agree, but JSON isn't really a wire protocol. According
to http://www.ietf.org/rfc/rfc4627.txt JSON is "a text format for the
serialization of structured data". There are some notes about encoding,
but it is very clearly described in terms of unicode code points.

In email's case this is true, but in JSON's case it's not. JSON is a
format defined as a sequence of code points; MIME is defined as a
sequence of octets.
