LGTM
Just a very tiny spelling nitpick :)

Some of your comments spell it "grey" and some spell it "gray". I guess everything should be "gray" since that's how Apple spells it?

LGTM too.
In material/colors.dart will spell "grey" which I think is the British version. For the sake of consistency, we should probably carry on with grey.

why do we pass 0 up to the constructor instead of just passing _effectiveColor.value and not overriding value?

Then the constructor can't be made const (#39430). IMO the benefit of being able to make a const CupertinoDynamicColor and use it in a function as the default parameter outweighs the cost, e.g.
const Color _kDefaultColor = Color(...);
class ThumbPainter extends CustomPainter {
const ThumbPainter({
this.color = _kDefaultColor,
}) : super(...);
}Now if I want to make _kDefaultColor a CupertinoDynamicColor, without the const constructor I'll have to break the API. Also works better with NNBD.

Description
Making iOS 13 colors compile-time constants. Since we don't change the appearance of widgets based on the OS version, dynamically updating color values may not be the best strategy. This would allow us to use these dynamic colors as default parameters.
