No I am saying why not train the divers for dives they are likely to do. Seems to me a few more dives at Cave 1 level and you can teach them how to do a jump or mark a T. This is what Naui and Gue do and I think it is a better way. I believe cavern, intro, apprentice and full cave are just more steps than needed. It is hard for intro divers to find buddies to dive with as no navigational decisions and 1/6ths is extremely limiting.
It's supposed to be limiting. It's suppose to give you time to fine tune what you've learned in class and get you ready for the next class. Intro/Basic/Apprentice are part of a curriculum. They were never intended to be stand alone courses. The ultimate goal was to become cave certified.
Going from OW gear to technical gear and taking all of those courses at the same time will not and does not properly prepare students or train students to master anything.
