I dsagree. Like many terms in photography, the meaning of that one has been diluted and confused in recent years. I and others use the term as I described in my first post above. And I use the words circular and rectangular to differentiate the two types of fisheye coverage.
BTW, I see that Merriam-Webster agrees with me:

My bad!! Yes, rectangular is the correct term. Thanks for straightening me out!
