I think the design system is a very good specification that can facilitate designers to collaborate with the team to design. The design system can present the results of research and design to the team in a more reasonable, clear and visual way. The design system provides a standard, clear and strict layout plan for beginners and designers. To some extent, it does make the design template-like, but I think this allows designers to focus more on higher-level creativity and improve user experience and process interactions without having to reinvent the wheel.
At the same time, the design system is also constantly summarized and improved in a large number of interactive designs. It is not a completely fixed plan, but a model and template that can be continuously improved and progressed over time.
