Same applies to `@viewport` and viewport dimension based preloading (picture, srcset, media specific stylesheets). A major downside of inlining is that with CSP, it will be off by default (and a security risk if opted-in to). We have nonces to overcome that, but they hard to deploy (need to change a secret for every page load). I'm hoping hashes will land soon, allowing to statically authorize some inline styles, without opening the doors for all style based XSS.
