Another difference seems to be that it applies only to --name-only, and
not to other forms. I can see how "-p --relative-names" might be weird,
because you'll get:

  diff --git a/../foo/bar b/../foo/bar

or something. But surely things like --name-status would want to support
it?

I suspect the ".." weirdness above is one of the reasons that --relative
restricted itself to the current directory (but regardless, I agree that
we cannot change it now).
