You're right that you still cannot do arbitrary media queries there. But from my experience (I'm not a designer though), staying within a set of predefined breakpoints (xs, sm, md, lg, xl) is often enough for most web pages.

The style attribute doesn't allow you to do anything responsive at all on the other hand.

That's what classes are for. (Which this also reinvents.)
