It's just using camelCased CSS similar to Emotion or styled-components, how is that similar to Tailwind at all, it's not atomic? Unless you simply mean that both Tailwind and VE have a build step, which is, well, vacuously similar. VE also runs PostCSS underneath after it compiles to CSS, so you can use whatever plug-ins you want too.

Regarding the QoL, it seems more to me that now Tailwind discovered that they have to support arbitrary CSS as well as every new feature, so they have to manipulate their DSL to fit all of that into their current syntax, ie class names, even if it doesn't fully fit. I'd rather just use CSS at that point, if I'm cramming a bunch of stuff into a class name.
