That's definitely one reason for the lack of step-by-step tutorials. Another one is that each product is so unique, with its own needs when it comes to later prototyping phase and then manufacturing.
Also, designing a enclosure is a completely different beast. Nowadays you would typically start out by 3D printing stuff and then later on in the process get it manufactured by injection molding. That means going to the factory and making sure that everything is set up right before they start the manufacturing the part. Again a very ad hoc procedure that's unique for every product.
