Ah, this does help!  The key piece I was missing was the idea of
appending to the list of weights in the pattern so that any explicitly
specified weight still came first.

I want to go from the default weight of medium on an ancient fontconfig
to a local user default of regular (i.e. matching newer fontconfig), so
I'm specifying regular rather than medium in my config:

    <match>
      <edit name="weight" mode="append" binding="strong">
        <const>regular</const>
      </edit>
    </match>

Thanks!
