Re: [csswg-drafts] [css-color-4] Resolving and serializing the opacity property (#8311)

I understand your concern about using `<'opacity'>` in other property value definitions. Productions of property value ranges embed the semantics of the property and are more often used in shorthand value definitions, or in properties that are semantically related: `background-blend-mode` with `<'mix-blend-mode'>`, `block-size` with `<'width'>`, etc.

I cannot find any property that only allows `<number>` to express an opacity or transparency value.
