I think it is just the start and saying it as good or bad may differ. In India, we are making it complex and have less flexibility in our education system. For example, a Science student has Maths and science as common but can you say that every science student likes Maths(ALdebra+Geometry) and Science (Physics+Chemistry+Biology). Some like science but not maths but for better career, they slog with it. If you are not able to clear your maths, but clear all other papers, you still is not considered pass but will have to repeat unless you clear your 1 remaining paper.
In many foreign universities, they do provide you optional subjects that helps you to get a valid certificate for every class you have passed. In Philipines, your Engineering degree is of 5 years, the 1st year is common when you clear your 2nd year, you are given and ITI certificate, upon completing your 3rd year, a diploma certificate, on completing your 4th year, you are an engineering graduate and upon completing your 5th year, you are a licensed engineer. It means that even if you leave your schooling in middle, you have a valid certificate. Here, in India, we have to clear every degree separately and if you are not able to clear, you don't have a degree even after going for 3-4 years.
The dual degree will help students to complete their family wish and even pursue his passion job. Many parents want their children to take up engineering but he would like to take commerce and on pressure, he joins the engineering degree. When we have dual-degree option, he would be able to complete his commerce and even take up the job that he prefer or wished.
