`background-clip: border-area` is a great example of something that you can use today — even though it’s only supported in Safari.
Progressive enhancement techniques let you ship something using it now, while supporting all users! When other browsers add support, more users will see the result.
The most powerful part of `background-clip: border-area` might just be what you can do with a round box and conic-gradient background on its border. Especially if you animate it using `@property`!
