You're right, so I should explain our rationale, and the WG can decide if we 
made the right choice.

Section 4.6 of RFC 9205 provides guidance to on how specifications should use 
HTTP status codes, and advises against being excessively specific about which 
status codes to use, due to the fact that they are often generated by 
components other than the application itself.

Given that, 409 seems definitely wrong, so we decided to revert it. Remember it 
was not itself the outcome of a WG discussion.

To resolve the question about the status code in this scenario, I propose the 
following change:

OLD:

   Redirect requests for searches, where more than one object is
   returned, and help queries, as described by [RFC9083], are not
   supported.  Servers MUST return an HTTP 409 for these requests.

NEW:

   Redirect requests for searches, where more than one object is
   returned, and help queries, as described by [RFC9083], are not
   supported.  Servers MUST return a 4xx status for these requests.

This would 400, 404, or similar, and is in keeping with the guidance in RFC 
9205.

Let me know what you think.

G.
