Somebody should note (might as well be me) that since the 1) the document is not a protocol specification & 2) the intended status is BCP, the use of RFC 2118 keywords is inappropriate to begin with.

[BA] Where does it say that BCPs can't contain normative keywords?  Lots of other BCPs seem to use them.

WRT this document, section 6 of RFC 2119 (sorry about the typo above) seems relevant:

6. Guidance in the use of these Imperatives

 

   Imperatives of the type defined in this memo must be used with care

   and sparingly.  In particular, they MUST only be used where it is

   actually required for interoperation or to limit behavior which has

   potential for causing harm (e.g., limiting retransmisssions)  For

   example, they must not be used to try to impose a particular method

   on implementors where the method is not required for

   interoperability.
