Designer here. My experience has been that Figma has done the opposite. It's created a lot of consistency with shared component libraries and standardized type / color styles. Also, the fact that engineers can jump into Figma and inspect CSS has been immensely helpful.
In the design world, Figma is like the equivalent of getting a robust IDE with syntax highlighting, code completion, compilation, and debugging. It's replaced multiple tools and connected people in a way that's never been possible.
