A point you are apparently missing is that musical notation has evolved from its origins in a reflexive manner. Music theory evolved from and with notation; I don't see why this new, progressive, more approachable form of notation would negatively impact learning and maybe even contributing to the evolution of music theory.

Just because something is new and unfamiliar does not mean it has to be scary. Just like fountain/feather pens are no longer all that widely used to write musical notation in a format that made sense for utensils, why does musical notation have to remain stuck in the past and cannot evolve?
