If the implementation is non-compliant, incomplete, testing, whatever, then why not let that be the case without additional requirements? Also, doesn't it create a circular problem with trying to indicate non-compliance in a compliant way? Especially if the non-compliance includes not providing those elements?

The purpose of this response is to provide more useful information
than no response at all.  Hence, there are additional requirements
to ensure that the response is worth receiving and to discourage
the sending of useless bytes.

They are conformant to the syntax of this spec, but not compliant
with the requirements of the DNT protocol (which includes both specs).

Useless bytes.
