That is simply untrue. Tailwind is great, but someone who isn’t proficient in creating css layouts is not going to magically understand the same layout with tailwind classes.

I had to eg. fix a stacking context issue (z-index) a so called full stack dev could not solve. Basic css technique.

For someone creating layouts from scratch tw is very verbose and templates can become difficult to reason through while you develop them. Easy to disregard for devs who just jump in a ready made template and make smaller changes.
