Also, the Airworthiness Certificate issued for the vehicle I regularly
fly does not anywhere describe it as a Glider, or as anything else.
There isn't even a box on the certificate where one would enter that
kind of information.

Mine does. My glider (one of my gliders) has a Special Airworthiness
Certificate (U.S. of A.) and has the word Glider in parentheses
following the word Experimental in the Category/Designation block.
This is in accordance with the (U. S. of A) FAA Order 8130.2E, Section
6, paragraph 121.d

My other glider has a Standard - also U.S. of A. But I did see a
round-motored Sukhoi or Zlin or some such aerobatic thing last
Saturday with OK registration flying the box in central Washington.
Must have been a long ferry flight!
