I note that you didn't write "MUST NOT". I heartily concur with "shouldn't" or SHOULD NOT. I still have issues with "MUST NOT".
Keep in mind that MUST NOT doesn't mean "do this and you will die", it means "do this and you won't interoperate" which seems exactly correct here.
SHOULD NOT means that you have external reasons to believe that you'll interoperate anyway, which doesn't seem right here, unless your plan is to send mail from your p=reject only to people with whom you have private whitelisting agreements.
