My issue with design systems is that inevitably the team using the internal companies design system has to implement custom components (usually early on) and try to match the feel of the design system already in place.

I'd rather go custom for a project and semi match the already in place feel of the company's UI standards. Then we're only bottle necked by our internal team and not an external team.

Thinking more on this, I'd love the https://tailwindcomponents.com setup for internal design components? Seems like the best of both worlds but does move the base from React/Angular components to Tailwindcss
