Just to reinforce this point: there are more than the two options that have been debated in this thread ("Node MUST NOT employ …" and "Nodes SHOULD NOT employ …"). For example, it would be possible to make a different recommendation for new implementations than for existing implementations: "New implementations MUST NOT employ …" and "Existing implementations SHOULD NOT employ …." It seems like this kind of formulation could assuage some (but not all) of the concerns expressed in this thread. Thus to me this consensus call would make sense with the caveat that if the document gets adopted as a WG item, the normative recommendation(s) will be different/weaker than the current "Nodes MUST NOT employ," without pre-judging exactly what the recommendation(s) will be (subject to further WG discussion).
