Additionally, I do not think, that copy pasting a CSS class name everywhere is a realistic sane use-case. Usually, one would render some template and that template lives only in one place in some file, not all over the codebase. If we go smaller than a template, to use jinja language, we have macros as reusable parts, also not having them all over the codebase. It rings like a gigantic strawman to me.

That is only the case for sites that include the entire, unpruned Tailwind Stylesheet with all utility classes. That’s a choice…
