Yes, there is certainly a design defect, which accounts for why so many
implementations have chosen to fudge their RFC 2047 handling in so many
ways.
The design defect is in the Usefor draft proposal, which requires
gateways to perform processing which in turn requires header field
syntax to be known, but which is *not* known in all cases, and cannot
be known in advance in the case of experimental header fields.
There are many more pieces of software than Usefor gateways which get
stuck because they do not know the correct way to parse some field. The
design flaw was in RFC 2047 which allowed that situation to be gotten into
in the first place.
As it is, many such systems currently use heuristics such as the one I
have proposed.
