I do agree, it's easy to abandon classes altogether. It's also a bit concerning that newer devs are starting with Tailwind. At the same time, I think one should be able to notice that certain styling is just getting repeated everywhere and abstracting it out makes sense.

What I actually like about Tailwind is not that you don't have to create classes at all, it's that you don't have to do it for things that don't need it. My old codebase was littered with hundreds of classes doing the same set of styling — padding, margins, flex-box stuff. That's the biggest thing Tailwind helps with.
