Re: [csswg-drafts] [css-color] We should consider addressing different use cases contemplated for contrast-color() with separate CSS functions (#11619)

Just the obligatory comment that WCAG2 contrast is not perceptually uniform (and it's not even close), is not supported by modern color or vision science, and is substantially wrong enough that using it in any automated function will have unpredictable/inaccessible results.

Worse, if designers get to the habit of setting contrast "by the numbers" (using the numbers of WCAG2), poor readability is the most likely result. This is especially true for dark modes, where WCAG2 fails most.
