Why does this matter? Adding inline styles through this method can guarantee that dependencies have been loaded before the code executes. That alone is important. But I’m excited by the potential this function brings to the table. As themes and plugins adopt it, caching solutions should be able to lock into it and move the inline scripts to external files that can be cached and even offloaded to a CDN rather than re-downloaded for every page view. I’m sure we’ll see solutions like Super Cache and Fastest Cache integrating quickly.
