To be fair Trevor Murdoch does the canadian destroyer as well though.
You see piledrivers in the WWE, but take a look at the one Orndorff hit Hogan with, it was an absolute belter, now that is not saying it wasn't just as safe as the ones of today, its simply that moves like that where considered an art form back then and years of working in different territories allowed those guys to perfect such moves
Now we have the WWE type wrestler
Orton
Kennedy
Rhodes
(and by the looks of it) Di Biase
Now I am not saying these guys are not good, but they all look like clones of each other in terms of either look and/or style
