It's fine if you don't want the WG to adopt this draft, but that second sentence is clearly wrong. The third paragraph of the introduction says:

      <t>The primary goal of this design is to provide faster negative
      responses to stub resolver queries that contain junk queries. This
      design will probably have little effect on getting faster positive
      responses to stub resolver for good queries on TLDs, because the data
      for those zones is usually long-lived and already in the cache of the
      recursive resolver; thus, getting faster positive responses is a
      non-goal of this design.</t>

Lookups to the root for things that don't actually exist in the root happen all the time, yes?
