I know it is conceptually "wrong" and a bunch of well crafted CSS classes would be more elegant. In the end it works, works really well and makes collaboration dead simple. Commonly used groups of classes can either be aliased by @apply or used in a (react) component. I used CSS way before Tailwind was a thing and in hindsight I created a lot of utility classes that resembled a weakly-structured, somewhat incomplete version of Tailwind.
It might be a bit verbose, it might be easy to abuse but it works damn well. On top of that there are some design guardrails built in that really help with the consistency of e.g spacing, colors and fonts. Easy to achieve good looking results without risking stuff always looking the same like with Bootstrap or Material.
It is a bit like Github Copilot. The only way to "get" it is to try it.
