[csswg-drafts] [css-color-4][css-color-5] Allow `<alpha-value>` to be `none` in `<color()>` (#7397)

cdoublev has just created a new issue for https://github.com/w3c/csswg-drafts:

== [css-color-4][css-color-5] Allow `<alpha-value>` to be `none` in `<color()>` ==
In [4.3. "Missing"/none Color Components](https://drafts.csswg.org/css-color-4/#missing):

> All color functions allow any of their components to be specified as `none`.

The value definition of `<color()>` is `color( <colorspace-params> [ / <alpha-value> ]? )` in [CSS Color 4](https://drafts.csswg.org/css-color-4/#funcdef-color) or `color( [from <color>]? <colorspace-params> [ / <alpha-value> ]? )` in [CSS Color 5](https://drafts.csswg.org/css-color-5/#funcdef-color).

Side question: is it voluntary not to export `<color()>` related sub-productions from CSS Color 5?
