Because an opening is "obscure" does not make it bad. I remember quite a few years ago the Center Counter with 1. e4 d5 2. exd5 Qxd5 3.Nc3 Qa5 was considered by most as a rather bad opening. I wrote a book on that opening anyway. And then played that opening in the 7th United States Correspondence Championship. And then [this was back in the late 1980s] slowly other people started looking at this opening. And then someone wrote a book and another book and the theory progressed to a world champion using that opening.
Back in the days of Morphy the Sicilian was an obscure opening but now we realize the Sicilian is a very viable opening.
Just putting a label on an opening does not make it a bad opening.
And while it is true I have played this opening for more than 25 years-I do not just play it out of habit and I have had much success with it and my play was with about 75% masters or above and 25% experts.
Also because Bruce Monson apparently loves and plays the Belgrade Gambit and because maybe that particular opening is not good--there is no anology with someone playing a completely different opening.
With your anology you could pick out someone who always plays 1. h4 and then say he has "Golden Hammer" syndrome and then compare 1. h4 with the Ponziani Opening.
What kind of success are you getting with equal opponents with this opening. The truth is in the pushing.
