Honestly, why don't they just add it to Safari as a css property?

I'm confident we'll have a ton of websites trying to replicate the Liquid Glass aesthetic, and will do so in a way that will eat half your laptops CPU.

As the article notes, with this in CSS, it's extremely easy to have different CSS depending on whether this is available or not. At the same time, it's not like other browsers don't do "non-standard" things.

I'm not saying I love Liquid Glass and I want it everywhere, but I prefer to have proper Liquid Glass everywhere on Safari, over having a custom unoptimized laggy unpolished version of it.

It's possible that they will in the future, but are still deciding on the API or implementation.
