I am going to push back here, hard. The draft is about names used in exactly one zone, and that zone has exactly one administrator. Your statement about "_any_ context" is inappropriate for this draft.

As a zone administrator considers what it can safely put in its zone, it follows policies. Most zone administrators in the world have no policies whatsoever, and thus the IETF should make it less likely that they will do something dangerous. However, that is not a concern for this zone administrator. They have policies up the wazoo and literally hundreds (probably thousands) of people helping make those policies and being sure they are implemented.

So, for this draft, restrictions that are being made because that one administrator might make an unnoticed mistake are harmful. It is fine to give advice about security and stability; in fact, Patrik is already doing this in his role on SSAC. This draft, however, is exactly the wrong place to make statements that apply to any zone other than the one in the title.

Bullet points 2 and 3 in section 4 should be removed.
