This has now landed in Chrome 66, would be nice to see it on caniuse.com

Added support for CSS Typed OM.

There's no blockers on Firefox other than time and resources now https://bugzilla.mozilla.org/show_bug.cgi?id=1278697#c10
It should be added to caniuse. It's on MDN.

It's on MDN.

Is it this one https://developer.mozilla.org/en-US/docs/Web/API/CSS_Typed_OM_API?

Then it's technically already on caniuse, via MDN 🎉

Following how MDN decided to split in in their support tables:
https://developer.mozilla.org/en-US/docs/Web/API/CSS_Typed_OM_API#browser_compatibility

=>

• https://caniuse.com/?search=CSSStyleValue
• https://caniuse.com/?search=StylePropertyMap
• https://caniuse.com/?search=CSSUnparsedValue
• https://caniuse.com/?search=CSSKeywordValue

But I still think a singular entry by caniuse itself encompassing all of this would be beneficial, giving viewers a table to quickly comprehend the support.

if CSS Typed Object Model API will be added, wouldn't that mean you would also have to add the other houdini spec names including CSS Properties and Values API etc. in addition to the individual components like CSSStyleMap, CSS at-rule: @property, etc.?
