I really really want to love this. I'm so close to loving it.

I'm a fan of utility classes. I don't think that classes should be named based on their content, or that we should be using stupidly specific and complex selectors so we can keep our markup clean (clean markup has nothing to do with class names or selectors); But I feel like this takes to too far.

What do I gain over inline styles? This doesn't seem to be too much more maintainable than that.

You gain a significant amount of performance. And readability. You would also lose a lot of the benefits of framework level variables with only using inline styles.
