It's the same as any DRY or optimised code: taking time and effort to make things overly DRY or optimised up front is a waste, building stuff out and then refactoring when you realise it's going to be repeated is a better workflow. With tailwind, that's simple because you take your string of class names, slap an @apply on it, and then use the new classname instead. No, it's not significantly different from just writing CSS then, but it's the workflow that's changed that reduces the friction between prototyping and then refactoring into a reusable design that makes Tailwind nice to work with in my experience (and I'm using it for a large-scale commercial project, not a landing page or static site).
