I think that type of thing is a dying art aside from professionally trained drummers.
eg: When I started playing drums (self taught of course... derp) it was also on a double kick pedal setup. My left foot never left that left kick pedal. My old(ish) timer drummer buddy who was one of the best I've ever played with stopped by a rehearsal just to hang out. He said he was impressed with what I was doing and how quickly I'd developed but seemed honestly upset that I hadn't started with my left foot on the hats before glueing it to the left kick pedal.
I got his point but I was learning (more or less) from scratch IN an already established band so I had to actually, yanno, play the songs and their ain't much hats pedal work in thrash metal. I said I could always learn that stuff later to which he essentially said "Naw, you already blew it. It's gonna be WAY more awkward/difficult now that that foot is trained to do what it's doing".
I was skeptical but darned if any time I tried doing hat pedal work it just was the WORST! I mean... just friggen ridiculous and felt oh so weird and wrong.
So I guess maybe you can blame the rise of the left kick pedal and/or schlocko self trained hacks?
