The deadest horse in web development is the myth of “separation of concerns”
You can separate concerns without violating locality of behavior, and that’s exactly what tailwind does.
It admittedly does not do a good job at being very DRY but I think that’s poorly applied to HTML/CSS in general, and the most DRY css is often over abstracted to the point of becoming nigh uninterpretable.
I was recently doing some very specific web scraping of some very public very static documents. About 25% of them use a soup of divs with hashes for class names. Not a <main> or <article> or <section> in sight. I am fine with the idea of what tailwind does but like at least using semantic tags where appropriate could be a thing.
