The maintenance is what makes Tailwind awesome. I've written CSS professionally since Internet Explorer 6 and have gone through many different strategies for writing maintainable CSS (BEM, OOCSS, SCSS and multiple different CSS-in-JS methods) but Tailwind is the first time I actually feel relieved of all the issues. To me, it's such an enormous improvement from normal CSS that people arguing against it feels like someone trying to convince me not to use syntax highlighting.
