Isn't that part of the argument of Tailwind being easier to scale?

I think that was true at the beginning. But Tailwind is quickly approaching the multi-headed hydra it was trying to replace.

What exactly has changed about Tailwind in, like, years? There are a few more properties for new CSS features, a few convenience features (like size-x instead of w-x h-x for the same values of x), but other than that? If you've grown accustomed to the utility classes eight years ago, then disappeared under a rock until today, you should be able to continue working in an unrelated, Tailwind-using project immediately.
