Existing practice is that localhost does not appear in the DNS.   The fact that the RFCs currently differ from existing practice is a problem that the current document is trying to solve.

No. That is localhost does not exist in the ICANN root zone, not that localhost
does not appear in the DNS.  There is a distinction.

   4.  (Caching) recursive DNS servers MUST respond to queries for
       localhost names with NXDOMAIN.

Is trying to to make it “go away”.
