Re: [csswg-drafts] OS cursor size units and property (#12048)

Primarily, I'd prefer the alternative. Try to get browsers to align that they should respect the setting proactively. That way users get what they expect by default and site authors don't lift a finger. Any exposure of fingerprinting is moot since no extra data is provided into the page context.

Doing some testing and research, it does seem I was mis-understanding how some things are handled between CSS and JS. There doesn't seem to be a way to get the final values of individual attribute computations. All we are doing is pulling the author-defined values in JS when we call for computed styles and such. (Aside from `element.matches` and `matchMedia` where we can at least get boolean responses.)

Given that JS has no way of getting a calculated final value out, my concern on fingerprinting seems like a non-issue. Just an instant late-night haze of a thought.
