I think your point has very little to do with tailwind and everything to do with CSS. Tailwind is optimized for modification and maintainability. We could replace your example with

<div class="hero-header hero-header--large">...

but now any time we want to modify hero-header, we're trolling through the whole site to find where else these classes might be used so we know what to test to avoid breaking anything

Sure it's easy to look at the element you shared and say it's too complex (it's really not, it's very declarative), but the complexity must live somewhere, and I'd choose Tailwind over any other prevailing system because it's isolated and safe to modify
