Even if the components are different, more often than not they will share same fundamental styles (margins, paddings, radius, colors) because of design systems.

Even if the components are different, more often than not they will share same fundamental styles (margins, paddings, radius, colors) because of design systems. What's the point of repeating all the standardized things again and again? Normally, you don't even need a component for something like a Heading, or Paragraph. With 'styled-components' you need to create extremely trivial components, that just need some styling. Conflicts aren't really a problem if your conventions are sane.
