Not sure what your point is, granted there is the occasional player who can throw hyzer from the start and turn over everything, but that is rare and at that point I would hope someone would recognize his natural talent and get a pro mentoring him or her very quickly.
But for the typical new player, it's simply better to start with lighter, understable discs so they learn to throw the hyzer early on which is the most natural release to throw a disc. And from there progression is made by slowly moving up to more stable, heavier discs.
Throwing a max-weight Nuke OS on a hyzer with a crapload of OAT and getting it to flip doesn't mean I should "progress" to something more overstable.
