Does anyone have theories about this part right at the bottom?

   /**
    * Placeholder fingerprint for Tor hidden service addresses.
    * Real fingerpritns will be fired by the plugins
    *   'anonymizer/tor/plugin/onion/*'
    */
   fingerprint('anonymizer/tor/hiddenservice/address') = nil;
   // END_DEFINITION

Does this suggest anything interesting about the ability to determine
either the physical location of a hidden service's service or instances
of people accessing a hidden service?

I also think that it's interesting that there's a category called
"documents/comsec", so the bigger picture is that there's an organized
way to find out about people who are interested in or becoming educated
about COMSEC.  It seems conceivable that documentation that I and other
people here have helped write is a part of other "documents/comsec"
fingerprints.
