I thought it might, especially since the Goju Ryu place, one of the instructors wrote a book about this same subject, but like one of the above posters said, "What are you asking? Just dive in and don't ask questions or go away." That's pretty much the attitude everywhere.
Haha ... I think basically it boils down to one thing, which is making money. The schools are for profit institutions so it behooves them to keep students around doing katas for years. If they had an applications class for general karate waza/bunkai without kata I guess they figure they'll lose a ton of business.
Two observations, which go hand in hand, on this issue...
The first is that, before you can take apart and understand the applications of a form -- you have to really know the moves of the form. My system has 5 main core forms; a typical student tends to spend about a year working each form. The smart students find themselves going back to the beginning and really spending time understanding and working with the form. The lazier, but still intelligent, students want someone to hand the application and uses to them. The laziest... Learn it, then dump it until their asked to regurgitate it for some reason. Most seem to waiver somewhere between wanting the applications handed to them and dumping it...
The second is that a commercial school is, first and foremost, a business. They're going to give the customer what they want... And many customers don't want to work the same form, again and again and again, ad infinitum. They don't want to drill a technique until they understand it. They want to spend 5 minutes, then learn the next thing. I was lucky; that's not how I was taught, though I was taught in a non-commercial school.
