The absence of info can’t be “additional” info. It’s a differentiating factor, but at best it’s on par with any other single info you would have sent through the font fetching request.
Arguably that single boolean characteristic (“fonts disabled”) is way less info than the dozens of characteristics you expose when fetching a font.

The non-boolean cascade of font fallbacks is too, but knowing that a user has a browsing context which should trigger one or more of those fallbacks, but doesn’t, is far more information than knowing that their browser behaves as expected.
- checkyoursudo 4y agoHow do you distinguish between passive failure and active disruption of your signal source? Unless you have yet another signal that can provide that information, then you cannot know that you have gained information by lack of original signal.

There will be a few edge cases missed by this but I think it holds for such a large percentage of cases that they can just assume it.
