Hi, Eliot, Tim, and Chris.

Tim and Chris, please advise regarding Eliot's question, bearing in mind that companion document RFC-to-be 9382 still has

In the meantime, it appears that the following is another good catch by Watson; we changed "therefore prevent" to "therefore prevents" in this document, as it appears to us that the meaning in this document is the same:
