Content standards in design systems support a holistically consistent user experience and efficient collaboration between writers, content, and UI designers.

The content - not the beautiful scroll animations - is the thing people use your product for. It is not lesser than. It is not an afterthought. It even has its own set of roles (content design, UX writing, information architecture, etc). The content is the scaffolding of the experience. When you minimize it, it is only to your own detriment.
