I would even say the answer is... however round "large rounded" should be. Tailwind doesn't force arbitrary opinions on these things upon you - it's a set of utilities to enforce your design system. If rounded means 6rem, so be it. There is, as you said, a single place to configure your design system (a CSS file, fwiw), which is objectively better than "well for these card-like containers we usually use 5px everywhere." Besides, I'm really wondering what sad jokes some people use to edit code that don't even offer tooltips for the styles getting applied by Tailwind classes.
