That (death) has already happened, and the result has been the various agencies doubling down on reducing their liability by restricting what instructors can teach.
Other than that, I agree the PADI MSD is BS, as are most specialty courses under most of the agencies.
I think there is too much emphasis on "instructor based training" and there is too high a regard that a certification card has any real meaning. But as long as there are people who believe that everyone around them shares in the accountability and liability for their choices and the results of those choices, then there must be a way for organizations and individuals to protect themselves...the impact of this is what we see in the industry today.

After reading and reflecting on what I wrote about specialty courses being BS, and what I know of training agencies I want to state the following:
Training agencies make their money by publishing and selling training materials along with charging administrative fees for the certification cards. Once a diver is done with a particular course, if they do not ever need a replacement card there is no flow of cash from the diver to the agency. The continual flow of funds is in annual fees paid by dive professionals (Instructors, Assistant instructors, Divemasters) who pay professional dues to be/remain affiliated with the agency. The cost of a training course, be it openwater certification or a specialty is not fully governed by the training agency. The instructor or organization providing the actual training (shop, club, etc.) is typically at liberty to set their own pricing to cover their costs for the training materials, admin fees with the agency, time, other resources, etc.
I can understand why a training agency would develop a robust menu of courses offered to divers. I also understand that some divers use these courses as additional time under the watchful eye of an instructor. I also know that just because the menu is robust does not mean the training courses themselves will be. The agencies are just looking to ensure they have a revenue stream that flows as much as possible.
My sentiment is that taking specialty courses does not necessarily make one a better, more competent, confident, and/or capable diver. It could but not always. I know plenty of divers with lots of cert cards and I question how they have not yet hurt themselves in the water....some of these folk even hold professional level certifications.
If taking courses is your bag, go for it. If collecting cards is your bag, go for it. If you believe there is some status or benefit to be gained by becoming DM certified, then go for it. If you want more time with an instructor, then go for it. If you want to hire a DM to guide you, then go for it. There are far worse ways on can spend their time and money.
