You are correct.  However, in my opinion, you are exploiting a bug.
The agent, as documented, should only accept groups on agentized
servers.

I'm not going to do anything about this right now.  I'm willing to see
how the public opinion goes.

Well, that's the idea.  Marking a server as agentized changes the
internals.  I'm still surprised that 'J u' functioned.

As for the faces, you can customize gnus-summary-highlight.  All you
need do is delete the three cons cells that reference the
gnus*undownloaded-face.

The following is completely untested.
  (dummy-variable (gnus-agent-fetch-group)) or
  (dummy-variable (gnus-agent-fetch-group "group.name"))

What you may not have noticed is that a new command has been added to
the summary buffer.  You can now execute 'J S' to do the same thing as
'J u' in the group buffer.
