Oh, I was replying to Michal.  I thought there was behavior difference
with the .use_hierarchy=0 cases that Michal was talking about but I
don't think that's the case and Michal is trying to say that we
shouldn't warn if the configuration behaves identical to
root.use_hierarchy=1 even if it contains some .use_hierarchy=0's,
which I'm fine with.

Thanks.
