The market for using second hand real 720 controllers out of busted cabs is absolutely as niche as it gets. If you looked up niche market it the dictionary, this might as well be in as an example. And in fact, it would be an extremely small niche market. Calling it niche would be an ego boost for this minuscule group of go-getters.
You're wrong about "people who are actually interested in 720". It was a childhood favorite of mine yet I'm not seeking out this option. I just want it to play on typical PC hardware. I wouldn't complain if there was a 720orig switch added to mame.ini that let you hook up a real controller, but I wouldn't put on whatever this public display of yourself is that you are doing either.
Again wrong with the Starwars comment. Lots of people want to play it and play it in MAME with a mouse. There's a niche market for these controllers with Ramcontrols or whatever they call themselves seek to fill.
I'm not under any delusions. I like how you think I'm the one out of line here yet you're the one pissing people off, including the people who could help your nichie cause.
