Struggling with this right now at my current job as one of four lead devs tasked with implementing our design system with using a React component library.

I am of the opinion that we only theme the components and provide snippets for how to use them for larger UI elements; the rest are of the mindset that we should be building more components in addition to the library for simple things like: a button that has a chevron in it for dropdown menus; a specific component for combining a tooltip with an info icon; a dialog with just an okay button, in addition to the dialog with both cancel and okay buttons; etc. etc.

Just the other day I got flak for saying no to accepting another version of a tooltip that had a different icon -- what's hard about using the tooltip with the icon you want...
