As someone that hates Tailwind, I think there is actually a use case here. If you are fluent in CSS reaching for Tailwind is probably a mistake. But for better or for worse there are lots of developers who can write HTML and JavaScript (or more likely React) who will not, and do not want to, learn CSS, for them things like Tailwind is a godsent.

I do think Tailwind is overused, but it obviously has some legitimate use case.
