Great. It seems a glob works:

On a sid test instance I just installed a few of the packages which currently ship woff files in /usr/share/fonts/woff

root at sid:/usr/share/fonts/woff# tree
.

Then I put the following snippet in /etc/fonts/conf.d/70-no-woffs.conf 

<?xml version="1.0"?>
<!DOCTYPE fontconfig SYSTEM "fonts.dtd">
<fontconfig>
<!-- Reject WOFF fonts
We don't register WOFF(2) fonts with fontconfig because of the W3C spec -->
 <selectfont>
  <rejectfont>
  <glob>/usr/share/fonts/woff/*</glob>
  </rejectfont>
 </selectfont>
</fontconfig>


And doing a fontconfig query I get:

So I think you solution works well. Thanks.
