Unless your X connection is not working, I believe you can safely

Well, more to the point for me... why does this happen? It certainly shouldn't, and I've done everything I can to eliminate the message.

You can't eliminate it, I suspect.

ssh is running the command

  xauth list $DISPLAY  (e.g. xauth list /tmp/launch-blah/:0)

and xauth is generating the output

xauth: (argv):1: bad display name "/tmp/launch-blah/:0" in "list" command

I'm not quite sure what the "fix" here is, since the Xauth data probably
isn't generated until the X server starts, which won't happen until sshd
requests that the forwarding happen -- and I think that may be after the
authentication data is transmitted to sshd.

Perhaps best would be to simply disable the warning in sshd for Darwin....
